So I've got the Boxee Beta running on two separate Apple TVs running 3.0.1 software and aTV Flash 4.0.5.
I mostly use the software to watch web content from TWiT, Mevio and Revision3 or listen to Pandora. So far, the experience has been surprisingly good. Video playback isn't perfect and is susceptible to occasional stuttering or audio sync issues that tend to resolve themselves. Playback quality seems highly dependent on the source. Revision 3's video quality is excellent; the podshow.tv stream of Geekbrief is great, but the same show on Mevio is very poor.
The biggest issue I've come across so far is that one box seems to lose contact with the boxee server after scanning through apps or browsing apps from the library a couple of times. Once this happens, none of my apps are visible, the software goes into a loading screen loop and hangs on exit.
Anyone else seeing this issue?
