I'm having problems seeking / with 4:3 to 16:9 transitions on RPi with the latest build (New OpenELEC Jarvis build #0830: RPi) using both the OMXPlayer and MMAL acceleration options. This seems to affect channels when they use different formats/bitrates for ads and shows.

Thanks for detailed bug report. I can see the cause of the MMAL issue. If you disable deinterlace it should work correctly again (would be useful if you can confirm that).

Basically the video_decode component can generate notification messages. One of these is aspect ratio has changed.
However when deinterlace is enabled we tunnel video_decode to image_fx (which does the deinterlace) and that's where the notification goes, and kodi doesn't see it.

I suspect I'll need to plumb in similar notifications from image_fx to fix this problem.
