I watch my locals in
HD the most (unles by locals you mean local programming on your ABC, NBCm, CBS or FOX station).
Considering that the most primetime programming is in HD nowdays (except for most reality shows), that is plenty HD to watch. IT is all more so convinent with my dual tuner DVR from Comcast. Let's me record 2 HD programs at the same time while I can watch a 3rd one that I previously recorded.
