I haven't seen this problem mentioned here. Sometimes when I go to live TV, the video is "choppy". Think a low frame rate video over the web. The audio is fine, and everything is synced, it just seems to be showing maybe 10 fps instead of 30. If I get out of live TV, to the main TiVo screen for example, and go back, everything is fine again. Anyone else experience this? Since it goes away easily, it's not a big problem, just curious.
