I have here an mpeg1 video, with sequence of 2 b frames.
I can trigger the bug with any mpeg with b frames...

mplayer -vfm ffmpeg -vf spp=0 -vo xv clip.mpeg
--> Looks like B frames aren't shown

mplayer -vfm ffmpeg -vf spp=0 -vo xmga clip.mpeg
--> The screen flashes between grey and the clip itself.
Pausing always pauses at the grey, never on the actual
picture.

mplayer -vfm ffmpeg -vf spp=0 -dr -vo xv clip.mpeg
-> Looks OK

mplayer -vfm ffmpeg -vf spp=0 -dr -vo xmga clip.mpeg
-> Looks OK

Tested with current CVS. Was reproducible on any mpeg with
B frames, so I hope it wont be necessary to upload sample...
