 Running r11417, I checked the revision logs and didn't see anything
 resembling this issue wrt current SVN.

 I recorded the Paris-Tours cycling highlights last night, which was the
 first programme broadcast on ITV4 after going on-air at 1800. I have a
 couple of minutes of pre-roll which meant the recording started whilst the
 channel was off-air. The resulting recording showed the ITV4 MHEG image
 "ITV4 Starts at 6.00pm" as I would expect.

 Whilst watching the recording today (or skipping forward until the actual
 program started), I noticed the audio stream started playing normally, but
 the video stream did not start at all, and the MHEG image was displayed.
 Interestingly, when I skipped forward through the recording to see whether
 the video would get displayed, I noticed that whilst the MHEG image
 persisted, whenever the aspect ratio of the underlying broadcast changed
 (the program was 4:3, the adverts 16:9), the AR of the MHEG image also
 changed accordingly.

 If I stopped the video after the program had started, and then restarted
 playback from that bookmark, the recording displayed normally with audio
 and video.
