I'm not familiar with a Channel Master brand of DVR, but I'm having a tough time understanding how a cable service can supply their DVR that record and function like a VHS. That's the whole point of a DVR, plus you can easily set it to record programs in advance. What exactly are you asking your cable company that they say can't be done?
Is there a DVR on the market that can directly replace a VCR? I don't want a subscription service such as TiVo. We have cable service and I want to record shows to play them later. The VCR is a bit clunky but works fine for this purpose. The ChannelMaster DVR cannot be used like a VCR, according to their response to my question. I don't care whether I have to brute force the program start/stop time on my own, since I am already doing that with the VCR. Thanks for any suggestions.
