bad modulator
Sounds like 1 of 2 things. Are you watching it on another TV not in the main room? I have a feeling that there is line loss and may need a line amp. Other possible thing could be that the channel you are on has OTA interference from a digital channel. See if changing the channel that is outputting from unit works better if you switch it to another channel. Look up what channels are really braodcast and be sure you are a couple away from those.

single node
Single mode here makes no difference. So it is only on TNT? Then it sounds like that they are doing something that is over driving the NTSC of the output of the RF modulator. That's the device that takes the signal and converts it to output the picture over TV channels.

Overheating can result in a jittery picture while audio is fine. Sometimes changing channels or pause/restart/rewind will fix it. You can check the 722s temp in Menu>6>1> (I believe it is 3) >counters. Scroll through the list until you find the Temps. Mine was reading as high as 129 when my picture was jittery. I moved the DVR to a location with better ventilation and placed it on 4 tall bottle caps. Has not happened since moving.
just confirming
Just trying to confirm it is only TNT and not other channels on the same polarity of the sat. We had someone say he was only having problems with a channel and then after getting him to check further it turned out to be all odd numbered channels.

Yes, only on TNT. I have checked the other channels and TP and only TNT is showing that issue. However today I have not seen the issue appear. But I have seen it happen twice within 7 days.
