I noticed that, about a week ago, I stopped seeing youtube rentals as a rental source in the TV and Movies app (for movies I know to be available in youtube rental). Can someone check and see if they reproduce this?
I also tried to playback a youtube movie rental I purchased from the Android Market on my GTV (both Sony BluRay and Logitech Revue). The flash plugin crashed immediately. Perhaps this is why the rental source has been removed?
