excellent! impressive interface!! some surprisingly great content (in particular a multi part documentary i watched on spacerip about robots) highly recommended. would certainly like to see more high caliber content, but then again, this is all free with no commercials, so i can't complain. (but do we really need more swimsuit channels? ugh-and i'm a guy...bring on quality content and sign up with more producers!!)
performance wise:
Penryn MBP, 6Mbit/640 DSL profile: not a single stutter, it played like butter. VERY FAST buffering, and CONSISTENT for every channel/show. impressive! not a single hiccup with hours of watching! Using my net monitor it seems the app uses less than 100k/sec, so again that's applaudable.
Quality of video is 8/10...respectable for streaming, but don't compare it to a dvd.....high motion brings the codec to its knees and pixelation is visible. by comparison, on stills it does a fantastic job.
a few minor bugs (cursor disappearing, some buttons get "stuck" in the explorer)
