On-screen messages

The core writes these over the picture when it needs to tell you something. Most clear themselves; the ones that persist are describing a condition, not an event.

Message	Meaning	What to do
CSS ENCRYPTED	The core is seeing scrambled sectors, so nothing available is decrypting this disc or image. Audio is muted to give you silence rather than static; video keeps playing so the disc stays identifiable.	Install libdvdcss, or use a decrypted rip — see What you need. If the picture is perfect and only the sound is missing, the message is wrong — please report it.
UNSUPPORTED IMAGE	Not an ISO9660 DVD image — a UDF-only image, for instance — or not a playable stream at all. Also a .wav the core cannot play (mono, 24-bit, floating point, 96 kHz).	Check the file is a whole-disc DVD image, or a 16-bit stereo 44.1/48 kHz .wav. See Compatibility.
Cannot play this CUE sheet	A .cue sheet could not be played; the next line says why (a missing file, an unsupported file type, a data-only disc).	See Troubleshooting.
AUDIO UNSUPPORTED	The selected audio track is in a format the core cannot decode.	Change track with B7 (press it twice: once to show the track, again to change it), or use passthrough. On a DTS track it means the DTS decoder could not load its tables at start-up — please report it. On an LPCM track it means the track's header declares a rate or word length DVD-Video does not allow (44.1/32 kHz, or an undefined word length).
TITLE VTS nn	Which title was auto-selected. Only shown with Disc Menus off.	Informational. If it picked the wrong one, Title VTS on the Debug page forces a choice.
LINK FAIL nn	A menu button's jump failed and the core recovered by re-entering the last working menu.	Usually harmless. If a disc is consistently unnavigable, it is worth reporting.
SEEK FWD 12:30	How far the pending D-pad seek will jump, while you are still tapping.	Informational — stop tapping and the jump happens.
No drive region: cracking	A physical disc is playing on a drive with no region set, so keys are being recovered from the disc data.	Playback starts in a few seconds. Set the drive region to avoid the wait.
Decrypting ISO	An encrypted image's keys are being recovered on first play.	Wait. It is cached afterwards, so this happens once per disc.

UNSUPPORTED IMAGE is patient by design

It is only raised after about 20 seconds of actual streaming with no picture. The timer counts delivered data, not wall-clock time, so slow media — a NAS spinning up, a cold USB drive — does not trigger it, and it clears itself if a picture appears.

A consequence worth knowing: a mount that fails outright delivers no data at all, so it produces no message. Silence means the core never got the file; UNSUPPORTED IMAGE means it read the file and could not play it. See Troubleshooting.

One exception, and it is immediate: a .wav whose format the core cannot play is rejected the moment its header is read, with no 20-second wait. The header states the format, so there is nothing to be patient about — and the alternative would be playing it as noise.

Support bundle

Needs MiSTer_DVDcss

New in v0.4.0, and only with the custom Main installed.

Shown when you hold Audio + Subtitle for two seconds to write a support bundle.

Message	Meaning
Generating support bundle...	Started. It runs in the background, so playback carries on.
Support bundle written to DVD_reports/…	Done — that is the file to attach to an issue.
Nothing to bundle	No image or disc was found. The lines beneath say what was seen; mounted: (not captured) with a disc playing is a bug worth reporting.
Support bundle needs dvd_report.py	Put dvd_report.py in /media/fat/Scripts/ — the release zip does this for you.
Support bundle FAILED	The collector errored. /tmp/dvd_report_run.log says why; the usual cause is a missing or very old python3.
Could not start bundle generation	The player could not spawn the collector at all.

Transport popups

These appear briefly when you change something, or when you press Audio or Subtitle to check the current track, and are not errors:

Popup	Meaning
AUDIO 2/4 FR	Audio track 2 of 4, French
SUB 1/3 EN / SUB OFF	Subtitle track, or subtitles disabled
ANGLE 2/3	Camera angle on a multi-angle disc
CH 12/23	Chapter, on a chapter step
TR 3/12	Track, on an audio CD — it replaces CH, since a CD has no chapters
►►►	Scrub speed while fast-forwarding or rewinding — two to five arrows, more the longer you hold

The status line along the bottom — ► 0:12:34/1:37:05 CH 12/23 — is toggled with B9 and also auto-shows for a couple of seconds on any of the above. ❚❚ replaces ► when paused.

In a pause, B9 decides on its own: a pause you start with B1 brings the line and the seek bar up, a pause you start with Frame Step leaves the picture clean, and B9 toggles either of them as often as you like. See Frame step.

While a seek is pending the time shows where you are going, not where you are. Hold Fast Fwd or Rewind, step chapters, or tap out a D-pad seek and the elapsed time tracks the seek bar's cursor, so the two always agree; it returns to the live position once the seek lands. On a .mpg, .VOB or VCD/SVCD the whole clock is an estimate worked out from how fast the file is playing — see VCD & SVCD.
