Ok, that's test.avi, very short only 10 frames inside.
Play it normally -> no problem.
Just add -vf bmovl=1:0:fifo (the fifo file doesn't even need to exist) ->
crash.

This one plays fine with the old mplayer.
1 file should be enough here. If you need the one which produces a bad
playing speed with bmovl enabled, just ask.

Well this one might be very hard. I thought vlc could play it, but actually
it can't neither. It detects 1 more subtitle track though (the teletext
one), but when you try to display any of these subtittles it just says it
can't handle this.
Anyway I have uploaded 2 versions : mp4/aac here :
http://dl.free.fr/mik7J66rL
and mpeg2/m2v here : http://dl.free.fr/iEAtPiYRb
Both in mpeg transport container. Dumped using mplayer -dumpstream, I hope
it dumped everything correctly...

I made the files very small (only 2 Mb), just ask if you need something
bigger here.

Thanks to take the time to have a look !
