I have an HD HomeRunPrime, it is great. It is a three channel tuner which works with Windows Media Center. I will do everything your DVR will do and use your computer's HDD to store the shows. The tuners are available to any Windows Media Center/Extender device on your network and you can point any other devices to your computer HDD to view anything recorded. You will need to rent a cable card and some box from TimeWarner to use the cablecard, but that should only cost about $3 a month.
I don't believe TimeWarner does anything proprietary. You should be able to connect a cable ready TV straight to their cable connection, but you need their box in order to view HD or work with any of the onDemand or special features like StartOver and such.
Hey everyone - thanks in advance for your help on this:
Like everyone, I'm trying to save some $$ and am switching most of my TV viewing to Hulu Plus instead of my Time Warner Cable package. I have a Samsung bluray player that connects to the internet, along with a Marantz receiver and an Epson projector. All that stuff works great.
My issue is that I still have the basic channels with TWC and I'd like to have the option to view them, but I don't want to continue to spend $20+ a month to rent their DVR receiver. If I had a normal TV, I'd just plug the coaxial cable from the wall into the back of the TV, but neither my receiver nor my projector have coaxial jacks on them. Sooooo I think I need a coaxial to HDMI converter?? But I'm not sure - and I'm worried that TWC has some kind of proprietary programing in their signal which will prevent me from using a converter I buy on Amazon or whatever.
