Small questions, useful answers
A soft picture at startup, Bluetooth delay or a guide entry at midnight can each have a different explanation. Choose the symptom below for a focused answer, a practical comparison and the relevant platform documentation.
Picture
Guide
Why does a stream look soft for the first few seconds?
A player may begin with a lower-quality adaptive stream and move up as it measures the connection; a soft start is different from a picture that stays blurred.
Read the guideGuide
Is jerky motion the same problem as buffering?
No. Uneven movement can occur while video keeps playing continuously; buffering usually interrupts playback while the player waits for more data.
Read the guideGuide
Why are the score or channel graphics cut off at the edges?
Cropping, zoom or television overscan can hide the outer part of a picture even when the stream itself is complete.
Read the guideGuide
Are black bars above a film a streaming fault?
Usually not. A film with a wider shape than the screen needs letterboxing if the full picture is preserved.
Read the guideGuide
Why can a sports feed look different at 50 Hz and 60 Hz?
The source frame rate and the display output do not always match neatly, so motion can look different without any change in download speed.
Read the guideGuide
What causes comb-like lines around moving people?
The picture may be interlaced and displayed without suitable deinterlacing; this looks different from blocky compression or a network pause.
Read the guideGuide
Why can an HDR source look washed out or unusually dark?
HDR playback relies on the source, player, output format and display handling the same dynamic-range path; a mismatch can change brightness and colour.
Read the guideGuide
Why does the screen go black briefly when a video starts?
A supported display-format switch can cause a short blank screen; repeated blackouts during steady playback need a separate investigation.
Read the guideGuide
Why can one source have sound but a black picture?
Audio and video use separate formats, so a player may decode the sound while failing to display that source’s video format.
Read the guideGuide
Why does one MP4 play while another MP4 fails?
MP4 names the container; the video and audio inside it can use different codecs and settings.
Read the guideGuide
Why does grass or crowd detail turn blocky while playback stays smooth?
Fine moving detail can expose compression limits even when the stream arrives continuously; this is not the same as buffering.
Read the guideGuide
Does the TV’s 4K input label prove the programme is native 4K?
No. It may describe the signal sent to the television after the streaming device has scaled a lower-resolution source.
Read the guideAudio
Guide
Why is dialogue late only when I use Bluetooth headphones?
The wireless audio route can add a different delay from the television speakers, so compare the outputs before changing the whole player setup.
Read the guideGuide
Why does sound work on the TV but disappear through a soundbar?
The soundbar connection or selected output format may not support the same audio path as the TV speakers.
Read the guideGuide
Why are voices quiet while music and effects are loud?
The programme mix and the way multichannel sound reaches your speakers can make dialogue harder to hear; this is different from a completely silent stream.
Read the guideGuide
Why is a voice describing the action between lines of dialogue?
An audio-description track may be selected; it is an accessibility soundtrack rather than a subtitle or buffering fault.
Read the guideGuide
Why can Windows sounds work while the player is silent?
Windows can give an individual app its own volume and output device, separate from the system sounds you hear.
Read the guideGuide
What does it mean when the picture freezes but sound continues?
The audio and video paths may be behaving differently; record that distinction instead of describing the whole stream as having stopped.
Read the guideGuide
How do I know whether to advance or delay the audio?
Judge a visible event against its sound, then make a small change and see whether the gap gets smaller; sign conventions and control labels can differ.
Read the guideGuide
Why does the volume jump when I change channels?
Different programmes and sources can have different mixes and loudness; a channel change is not a controlled test of one fixed audio signal.
Read the guideGuide
Why can surround sound behave differently over optical and HDMI?
The connection and receiving equipment can support different audio formats, so an output that works over one route may not work identically over another.
Read the guideGuide
Why does lip sync change after I skip forward?
A seek changes the playback position and can expose a source or player timing problem that is different from a constant output delay.
Read the guideSubtitles
Guide
Why do subtitles remain visible after I turn them off?
They may be burned into the video picture rather than as a separate subtitle track.
Read the guideGuide
Why do subtitles show strange symbols instead of letters?
A text-encoding mismatch can make subtitle characters render incorrectly even when their timing is right.
Read the guideGuide
Why do subtitles appear only for a few lines of dialogue?
The selected track may contain forced translations or signs rather than subtitles for the complete programme.
Read the guideGuide
Why do captions include names and sound effects?
An SDH or closed-caption track can include non-dialogue sounds and speaker information to make the programme more accessible.
Read the guideGuide
Why does a subtitle fix work at the start but drift later?
A fixed offset can correct a constant timing gap; it cannot necessarily correct a track whose timing increasingly diverges from the programme.
Read the guideGuide
Why does changing the subtitle font have no effect?
The track may use images or its own styling, so it may not respond like an ordinary text subtitle.
Read the guideGuide
Why are the bottom lines of subtitles missing?
Subtitle placement, video zoom or the screen’s picture-size setting may be pushing the text outside the visible area.
Read the guideGuide
Why do subtitles disappear when I cast a video?
The receiver’s playback route may not handle the same subtitle format or selection as the app on the sending device.
Read the guideNetwork
Guide
Why is a 100 Mbps connection not the same as 100 MB/s?
A byte contains eight bits, so 100 megabits per second is 12.5 megabytes per second before other transfer overheads.
Read the guideGuide
Why does playback struggle when another device uploads files?
A busy connection and growing queues can affect responsiveness even when a separate speed test once showed a high download rate.
Read the guideGuide
Does a 100 Mbps Ethernet link mean my cable is faulty?
Not necessarily. The negotiated link rate depends on both connected ports and the cable path; some devices are designed with a 100 Mbps interface.
Read the guideGuide
Why can’t my phone find the TV when both show Wi-Fi?
They may be on networks that cannot communicate with each other, such as an isolated guest network, despite both having internet access.
Read the guideGuide
Why does hotel Wi-Fi connect but the player still has no internet?
The network may require a browser sign-in or other captive-portal step before it permits ordinary internet traffic.
Read the guideGuide
Does a stream working with a VPN prove the ISP blocked it?
No. A VPN changes the network route and other connection conditions, so the result narrows a comparison without proving one cause.
Read the guideGuide
Can changing DNS fix a video decoder problem?
DNS helps resolve names to network addresses; it does not add a missing video decoder or rewrite the source’s encoded picture.
Read the guideGuide
Why can a stream stutter even when Wi-Fi shows full bars?
Signal strength is only one part of wireless performance; interference, contention and the wider connection can still affect delivery.
Read the guideGuide
Why does playback work in the morning but struggle in the evening?
Conditions can change over the day, including household traffic, wireless use and the path to a source; timing alone does not identify which one changed.
Read the guideGuide
What does it mean if restarting the router helps only briefly?
It shows a temporary change in conditions, not proof that a permanent fault has been repaired or that the player was responsible.
Read the guideGuide
Why can a casting session fail when the phone changes networks?
The sender and receiver use a particular local/network relationship; leaving that network can affect control or the playback route, depending on the app.
Read the guideGuide
Can a live preview count as an active viewing connection?
It can be a real playback session, so close the first stream before testing another screen on a one-connection account.
Read the guideProgramme guide
Guide
Why does a late-night programme appear under a different date?
A guide can use a different time zone or day boundary from your local clock, especially for broadcasts close to midnight.
Read the guideGuide
Why did programme listings move by one hour after the clocks changed?
The device zone rules, guide timestamps or an old manual offset may not agree after a daylight-saving change.
Read the guideGuide
Why can a channel name be right but its programme guide be wrong?
Guide mapping can depend on an internal identifier rather than only the visible channel name.
Read the guideGuide
Why does a player ask for both a playlist URL and an EPG URL?
The playlist identifies media entries, while the EPG source supplies programme schedule data; they can be separate resources.
Read the guideGuide
Why can I see yesterday’s programme but not play it?
A stored schedule entry describes what was broadcast; it does not by itself provide a replay recording or permission to access one.
Read the guideGuide
Is pausing live television the same as catch-up?
No. A player/backend can buffer an active session for timeshifting, while catch-up retrieves an earlier programme through a separate supported replay route.
Read the guideGuide
Why does today’s guide work while tomorrow is empty?
The schedule may not extend that far yet, or the player’s imported/displayed guide range may be limited.
Read the guideGuide
Why can a replay start too early or finish before the programme ends?
Replay selection and guide timing may not line up precisely, and the available replay media can have its own start, end and seeking behavior.

Guide
Is the playlist name the same as my account username?
Usually it is only a local label; the actual login fields or issued playlist address are what identify the service account.
Read the guideGuide
Why can a playlist link break when special characters are copied or edited?
URL punctuation can have a structural meaning, so changing or losing characters can change the address rather than merely its appearance.
Read the guideGuide
Why can a pasted login fail when typing it works?
Copied text can include spaces, line breaks or substituted punctuation that the login field treats as different characters.
Read the guideGuide
Can I use the website address as the player’s server address?
Only if the account instructions explicitly identify it as the server; a marketing website and a media-account endpoint can have different addresses.
Read the guideGuide
Why can a web player work while the desktop app fails on the same computer?
The browser and native application can use different media support, saved settings and network paths even on the same computer.
Read the guideGuide
Why can the app show a licence warning while my service term is still active?
The player developer’s licence and the streaming service account can have separate expiry dates and payment arrangements.
Read the guideGuide
Can I enter my order reference as the player username or password?
No. The website reference identifies the saved request; player access details are through the account-activation process.
Read the guideGuide
Why should I compare the publisher when two apps have the same name?
A familiar name or similar icon does not establish that two listings are the same software, developer or supported account route.
Read the guideGuide
Why does an old favourite fail while the channel in the main list works?
The saved favourite may still point to an older entry or source identifier after the catalogue changes.
Read the guideGuide
Will a factory reset repair one channel that will not play?
A device-wide reset is a broad, disruptive action and is not a focused first response when other sources already work.
