i have a PSP and have been testing mencoder and ffmpeg.  unfortunately i 
have found that mencoder sometimes generates files that the PSP will not 
play completely.  it will start and play for a while but eventually the 
PSP will stop and display "cannot play this movie."  i haven't isolated 
why it happens.  i suspect the bitrate may be peaking above what the PSP 
can handle.

this is a bummer because one of my use cases is converting WMV3 to PSP 
and of course only mencoder can read WMV3.
