Hi there,
For those of you who don't know it yet,
http://www.gametube.org probably provides the best quality around since Stage6 closed.
BaronSoosdon, Olibith and many other great moviemakers have been using it for a while now :-)
Current version allows you to stream any gaming-related (strong focus on WoW) video 800kb/s with maximum keyframes for a smooth playing.
Next release (coming soon) plans to bring 1,5mb/s H264 videos for all.
It's fast, free, got a alot of available bandwith and has a cool design ^^ No length/size restriction for your files.
Hope you'll like it ;-)
