I have an older Panasonic plasma display (no tuner) that I would like to pair up with a DVR that has a clear QAM tuner for cable. My cable provider has several local HD digital channels available without using a converter. I found a Toshiba that records to DVD but I would prefer a HDD. I really don't want to rent another $30 HD DVR from the cable company as this TV doesn't really get a lot of use. Does anyone make such a device?
