Mike Taulty's video (MEF & Silverlight 4 Beta) is pretty pixelated at the beginning, but it gets better in 10 seconds or so, and becomes crystal clear after just 15-25 seconds.
Same experience as me, blocky and pixellated to begin with, but much better quality later. I get about 120-130ms ping to smooth.ch9.ms btw.
But my issues with C9 were rarely with the streaming (and when I did have streaming issues it was because I had a dodgy connection), they were mainly with the player. Speaking of which, are video streams resumable? If I'm watching over wifi and lose my connection,
does the player have to redownload it all when I get reconnected or will it keep its buffer and play what's been downloaded?
