I have heard about a great many problems with the 2.1 software. I thought that it would be a good idea to house all of these questions in one thread. Maybe I'm wrong. MY situation is that the 2.1 upgrade made the video from streamed and synced content jerky. The remote control was slow to respond to even simple commands like "up", etc. I downgraded to 1.1 and now the remote works smooth as butter and the video isn't jerky or anything. What gives?
