 Hello

 I've compiled ffmpeg _without_ support for AC3. Then I've tried to
transcode some .vob file into DVB transport stream, and got following
result:

[master at skifo ffmpeg]$ ./ffmpeg -i /media/cdrom/VIDEO_TS/VTS_07_2.VOB -f
mpegts -vcodec copy -ar 44100 gits.ts

I hope it's easy to reproduce. This problem stoped to occure when I
compiled AC3 support (--enable-a52).
