Actually, my youtube started working. Finally web videos showed up in parental controls (it wasn't there before)...........
It took a few hours to show up........But I think the problem lies within the router.......With my Belkin, I had to enter ports and change from TCP to UDP.......once I applied the settings to the router, then rebooted the receiver, it started working and the tv apps initializing error went away.........A few hours later, youtube showed up.
It works fine but I was hoping when I did a search for my user name it would pull up my favorites and or playlists.......
Say you have a playlist with 20 videos you want to watch.......Once the first vid is done, it automatically goes to the next one........But I don't think this works with the Youtube smart search .........I'm still playing around with it so I don't know
