I have an HD Series 3. I used to be able to access youtube with it, but its been quite a while since I tried and I don't see it now. Under Music, Photos and Showcases I see pandora, Live365, Podcaster and a few others, but no Youtube. If I select the Video on Demand from the main menu it just goes back to the main menu. The network connectivity is fine, it regularly connects and downloads the schedules. Any ideas what happened to Youtube?
