Did you add --ttl 64 to the commandline of VLC or VLS ? Further are you 
using unicast or multicast streaming?

You need to do:

% ./bootstrap

A normal stream from DVB card occupied 3.5 - 5 Mbps, a DVD occupies 8 
Mbps and a file ?? who knows it largely depends on the codec, width and 
height of the video and colordepth. Streaming over a 56k modem 
connection is not possible unless you downscale the video very 
drastically. Downloading through VLC streamer http or ftp output is very 
well possible. It only takes very long ;-) Viewing is only then possible 
when the complete file is downloaded on your client.
