That has nothing to do with it. I hate their stupid guide plus having TV's, and sometimes those things will change channel numbers, but not the actual channel. All this is compounded by customer's who pay $100s of $$ for tvs then LOSE the remote! I prefer Sony and Sanyo, with magnavox coming in a close 3rd. The only thing worse than an RCA is a cheapo walmart after thanksgiving day/christmas special.
Back in the early days of HD, RCA used to build d* IRDs into the TV. I would go do an install and then not be able to activate for some BS reason or other, always involving the access card.
