When watching certain (not all) SD channels in "panel" mode (as TiVo calls it) I get the grey side bars. However, on the left side, between the show image and the grey side bar is a black side bar (about an inch wide). Happens on FX, TNT, CNBC, MSNBC (among others), but not on CNN, Spike, Bravo (among others). I tried tuning the problem channels on my TiVo Series 2, and my Comcast/Moto HD DVR, and the issue only exists on the THD. While I don't always watch SD in panel mode, it's annoying to have the extra black bar, and is also a screen burn in issue. Anybody else have this issue? Anybody know how to resolve (TiVo support couldn't help)?
