I was watching Encore HD today and during a movie (Dumb and Dumber) the screen went all yellow, (no sound, no picture, just a blank bright yellow screen), I noticed it the other day as well during another movie. I switched to the SD channel and everything was good but the HD one stayed yellow when I switched back (I can't be sure exactly how long, since I gave up after 5 minutes), although I did check and my signal was fine. Has anyone else experienced this? I'm using a VIP222k. Thanks.
