You may have to drop the capture resolution. I'm using NFS over switched 
100Mbps, and at 480x240 RTJpeg, it's not a problem in the slightest. A 
teeny lag in display after changing channels, but otherwise fine. I'll 
report on higher resolutions when I've got the hardware encoder installed 
:)

Gaah! Why would you want to pipe decoded video across the network? That's 
horribly wasteful of bandwidth! Have the client decode the video.

Well, I'm just about right out to beer, so take my $0.02 with a grain of 
salt :)
