Seems like we have at least two distinct problems with video playback with PR1.1

The first is lack of video when playing back xvid files over upnp. This is tracked as https://bugs.maemo.org/show_bug.cgi?id=8000

The second problem that people, including me, have seen is (usually) h.264 files failing with an 'infinite 5 flashing dots' error when played locally and 'infinite buffering' when played over upnp. I did some investigations and the results are surprising.

It appears that this is caused by the presence of chapter marks in the files. My files with chapters don't play and the ones with no chapters do not play. Of course, the media player doesn't support chapters so getting rid of them isn't a loss (but re-muxing files is a crummy work around) but there is clearly a regression here.

Unfortunately, my HandBrake preset that we've all been using has chapters turned on by default. I've updated it (still hosted on my server) so anyone who grabs it now won't get trapped by this.

I've filed https://bugs.maemo.org/show_bug.cgi?id=8172 to track this.
