[MPlayer-users] Putting motion back into an mpeg-ps stream

[PO]

Hi all!

I'm going from a divx5 format avi with no b frames to a dvd mpeg-ps file 
for playback in a standalone dvd player. The problem with the final file 
is that on high motion scenes the playback becomes jerky, the result of 
no b frames, I assume. what would be the best way to do such a task? Is 
there a filter I can add to the -vf option that will fix this?

Here is what mplayer sez about the original file:
