I know we are often at the mercy of our cable providers for what cable box we have. I was thinking about going down to my local Time Warner branch office and see if I can get an upgrade. I've had the same box for 2+ years and I'm sure there has to be someething better out there. Do cable boxes do any special processing to the signal (akin to DVD player digital processing)? Do we as consumers know anything (I obviously don't) about what different models of cable boxes are out there, and what are the newer ones?
