[MPlayer-users] vop not coded

Hi. I'm trying to play a video file, but I'm getting jerky video on my  
system (1.07 GHz iBook G4, 256 MB RAM). I get the following error  
during playback, but the file keeps playing:

vop not coded 0.3 A-V:  0.533 ct:  0.028    8/  8   0%  0%  0.0% 7 0 0%

It's the "vop not coded" part I don't understand. After that, I know  
what's going on. It appears for quite a number of lines, at an almost  
frame-to-frame interval, as best as I can guess. Below is the -V  
output:

Exiting... (Quit)

I wouldn't be quite so alarmed, except that the file plays perfectly  
fine on my XBox (MPlayer in XBox Media Center), which runs off of a  
Intel Celeron 733, which eliminates processing power as a question.  
Data rate is also ruled out. This file streams off of my server to the  
XBox at a maximum speed of about 500-700 KBytes/sec while it's playing  
from the hard disk of my iBook. The file plays mostly smooth in  
QuickTime with a few compression artifacts showing up here and there  
from dropped B frames (or that's what it looks like). Any ideas?
