I don't use YouTube at all, so I don't know. I can check though. I can also check using SageTV to see if it's working there. It doesn't use a YouTube app.

The latest firmware is better and almost worth it alone for the better sorting, but it still has plenty of issues. Like I said, I don't think they'll be able to get through all the issues in any less than a half dozen updates over the next 6 or so months.

My biggest complaints right now are still the scanner, video playback buffering and UI/remote unresponsiveness at times.
