Right now anyone with Flash can stream from the main site, www.youtube.com (but getting Flash is harder than it should be for 64bit Linux users). You can also go to their mobile site, m.youtube.com where the video is available as 3gp streamed format (video is H263, audio is mono "samr" aka AMR). I can watch this in VLC but with no sound - but from googling I think that will be sovled eventually. I was wondering where (i.e. URLs) the AppleTV gets its H264 encoded high quality YouTube content from. I'm sure someone with an AppleTV could simply enable a firewall log or sniff the network traffic to work this out... Ideally I'd like to be able to access the H264 YouTube from my web browser. Alternatively, is there any sign that Front Row on the Mac will support YouTube too? P.S. Does the iPhone have access to yet another version of the YouTube content, or is it the same as m.youtube.com ?
