2576	Video stream does not  replace MHEG image when channel transitions from off-air to on-air (UK,ITV4)	knowledgejunkie@…	danielk	"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.
