Watching live TV through Tablo frequent freezes

I’ve had my Tablo several years, not sure what model it is. For some reason it picks up the channels better than my TV does. So when the TV is hard to watch, I switch to Tablo to watch. This generally works well, but frequently it will just pause for several seconds. Then it will continue at the same spot, with a skip typically, and the picture will be good, like it received fine. Sometimes the freeze doesn’t fix itself, and I have to go out of live tv mode on the tablo, or maybe to the TV. This seems to happen more after I’ve been watching a few minutes.

Does anyone else use a Tablo like this, and if so, does this happen to you guys as well?
