This is streaming over a gigabit lan, so I doubt I'm dropping packets! 
What I do see in VLC's streaming information window, however, is that 
the resolution is way off -- in the mencoder-encoded files, it's given 
as 16x320, where the fact is 640x480, or 16x16 for some odd ratio much 
larger. Mind you, the picture size is the correct one, so this may not 
signify anything.

This may actually have helped -- the picture looks somewhat better. But 
it's far from the perfect picture I get with streaming files encoded 
with ffmpeg.

With  vlc $1 -I dummy --sout '#std{access=mmsh,dst=:5003}' --ttl 12 --loop;;

I tried adding in the width and height, but it made no difference. 
ffmpeg shows the resolution correctly.

Am I the only one with this problem? How are people encoding their 
streaming x264 files?
