They're claiming that they cannot simply trap out the digital channels from those getting the analog Basic service, even though the digital goodies start way up at channel 64 and the analog tops out at 30. "Traps don't work", according to customer service. (Someone please explain why RF traps care what modulation is on the frequencies they filter out, or how a trap that makes analog signals undetectable will provide a viewable digital signal when even an unfiltered digital signal drops out on a regular basis.) This is the same cable company that used to be able to trap out channels 31 and above if you didn't have Expanded Basic.
They point the finger at the program providers — like ESPN and SyFy. "It's a contractual requirement" for people who are paying for the programs to be prevented from using their own DVRs to record them for later use. "Of course we'll rent you a Comcast DVR..."
Perhaps it's time to dust of those old copies of the Cable Consumer Protection Act of 1992, which deals specifically with this issue.
