A couple of times now, my VIP612 has exhibited this problem. While recording two channels at once, and playing back an already-recorded show, the picture will freeze at some point and the receiver will not respond to any remote commands. At this point I can either reset the receiver and try again, which usually brings up the same problem in short order, or just leave the receiver in the 'hung' mode until the two shows being recorded are over. Evidently the recordings continue even though the receiver is frozen and not responsive, because they can be played back just fine at a later time. Is this a known situation? Is it expecting too much of a two-channel recorder to play back a previous recording at the same time it's recording two different channels? I'm hesitant to bother Dish with this because it's an old receiver, and to replace it with a current model would probably drive the monthly cost up. Thanks!
