The VIP211k unit that I have in my bedroom is having an issue with jerky video. It started this morning after working fine last night. Been having this box since September or so. I tried rebooting it with the button on the front. Same issue. I went through a couple of other menu screens and exited out of that...it fixed the problem for about 45 minutes. Doing it again now. When you go to the guide, the in screen video box is running just fine. Any ideas on this one guys? Thanks!
