I'll keep this short..
UK owner. Problems reverting to 0.9 & missed downloading the 0.9 ISO posted elsewhere. Got the black screen w/sound with all content so restarted, now YouTube HD content plays but from a usb hard drive video is choppy at best, at worst just a small part of the screen refreshes every 5 seconds with a thumbnail of the movie... Have changed HDMI cable, same same. TV is a 47" lcd JVC, about 2 years old, 1080p and content from the same hdd played fine using a WD TV Live (which I sold before the Boxee arrived).
Is this what the finished 1.0 product does, or is my box faulty?
