I've had my VIP 722 for over a year now and recently have noticed several problems. Most of the problems comes when I'm recording two shows at once and trying to watch a third on the DVR. The menu's will move very slowly, if you press a button too many times, it will eventually "catch up" and move through a bunch of screens. Playback is jerky, sometimes in slow motion even though I'm in play. If I watch a delayed event, it will sometimes skip ahead to LIVE even though I'm at the beginning of the show. I would assume the hard drive is failing. If that is the case, I realize I can call support and maybe get a new dvr sent out....or I can add a external hdd and transfer my shows (I'm about 80% full anyway). I've disconnected power and re-booted. Any other suggestions?
