i have two files here, but read below please

i don't know how to tell mplayer to use lavf-demuxer (manpage gives no
hint), but i tried my own player with libavformat and it works correct.
I should have tried that earlier.

I am very sorry!
ffmpeg is correct here.

So this is clearly a mplayer bug.
It is even worse with files encoded with b_pyramid-flag.

I relied too much on mplayer, so far it worked for all files and i
searched some hours in my code and was frustrated, sorry for bothering you

Thanks for your reply and your time!
