My mom's old console TV is dying. She currenlty has the basic tier of Comcast (formerly Adelphia) digital cable, with the set-top box. She likes the digital music channels, but at age 78, having a separate tuner box can be confusing at times. I'm helping her shop for a new TV, and I'm debating whether it would be worth limiting our search to sets that have a QAM tuner. I understand the tuner will only provide digital cable signals that are unscrambled, but the question is: how much of what my mom currently gets on her set-top-box is unscrambled? A comcast CSR told me it would only work if the set has a cable card - and in the price range we're looking at (under $600) I don't see anything with a cable card. There are a handful of JVC and Toshiba models that have QAM tuners - but other models we've looked at (like Sony and Insignia at Best Buy) don't offer QAM. Any advice?
