Comment (by J.Pilk@…):

 {{{
 This box is now running 29-pre-386 with the updated (20170414) patch.
 Previously it was 29-pre-189; ie, before the ffmpeg resync.

 I set up two recordings:

 CBeebies 18:56 - 19:04 BST    displayed length 2:07.880, 3197 frames
 Playback normal, with sound; goes to black screen at 02:00.600.  Probably
 18:58 BST

 Audio streams shown as
 1. English MP 0 ?ch
 2. English (Audio Description)
 -----------

 BBC Four 18:58 - 19:34 BST    displayed length 35:09.720. 52743 frames

 Playback starts at the 'Mythical' bookmark, 02:00 or 3000 frames.  That
 will be 19:00:00 BST.
 There's no sound, but the Audio streams identify as above.

 If playback is started with the edit cursor at the start of the recording,
 I see a static
 ident screen for 12s, then BBC programme ads, with sound, until the spoken
 intro at 01:01.040

 When I started compiling this, I could get sound while editing.  Then it
 disappeared.
 Very confusing.  Eventually... playback and editing seem to be almost
 normal if playback was
 started from the beginning.  But the log has a selection of repeated
 warnings, probably mainly
 from jump tests.  I haven't tried correlating them with my commands.
