sorry -- sent that last message before I was ready.

When I run mplayer on the test.ogg file created by ffmpeg, seeking
causes audio/video to go out of sync with the following error:

[ogg @ 0x8b7a300]Broken file, non-keyframe not correctly marked.
[ogg @ 0x8b7a300]Broken file, non-keyframe not correctly marked.

I've prepared some files, alone with a shell script called test.sh
which reproduces this problem.  They are here:

mplayer.txt containes the output I got from

> mplayer test.ogg &> mplayer.txt

ffmpeg.txt contains the output I posted before.
