can anyone confirm if it is possible to output the video to TV using AV cables?
I see no reason to believe this will ever be possible, the AV cables only output ipod videos, no menus and no other app content. Yes some developers have been shown outputting their games onto a tv during testing, but this is not going to carry over to a user experience (at least not yet)
I was using the Apple AV cables and it worked for me with the Youtube app. It might possibly work. I don't have a way to test this until I get back in the US and get it set up though.
