As Comcast has pretty much moved to all digital and most of that is encoded in a proprietary way the days of using any old DVR is coming to an end. Your other requirement reduced what might have been possible to nothing out there.
I think no is the answer given the specs.
Do most of the DVRs work with some/any/all the cable companies? I want to purchase one, eliminate the rental fee, and keep a consistant interface when I switch cable companies.
Three tuners would be nice as would the ability to plug in a terabyte hard drive. I am willing to open it up and plug one in, and maybe even hack it, but get no big thrill out of that.
Do any of the DVRs categorize the recordings? When I go to select a recording to play I could select the hers or his category and reduce my search time. More categories would be better.
Thank you for your time
