There are a ton of video sharing sites floating around now and most of them are crap - slow, poor quality video and no decent content.
I’ve been using DivX Stage6 since it came out and it’s the bee’s knees. You do have to install a small plugin but then you get huge, clear steaming video.
I use it to watch UK/US TV shows (mainly Top Gear). I have a computer plugged into the TV and I can stream stuff in realtime at way better than cable TV quality.
Seriously, it’s friggin great, try it!
Excellence.
