One of these is new, the other two have been around forever (saw them on my old Elite for years too). - With 20.4.2, I'm now seeing an occasional black video screen with audio when playing from menu (i.e. no video). Have to go back into menu and play again to get working, trickplay has no effect. - When chase playing an in-progress recording and I'm almost at the end (i.e. caught up to live), I routinely see the box lose track of where I last watched if I exit out and play another recording. Pausing before backing out has no effect, it just randomly decides that you can only restart from beginning with no option to resume from last point. This is REALLY annoying when flipping between sports that I've recorded, which happens all the time on the weekends, and it only seems to happen if I'm within a minute or two of live when backing out. - Occasionally when skipping around a recording I'll get mono instead of stereo sound until I skip forward/back or exit out and replay. Both of the last two bugs have been around forever, the first one is new. I'm particularly peeved that the second one has never been fixed since you'd think Tivo would've seen this before, it's not like it's rare.
