I've currently got my nice shiny new PC, on which I play WoW and occassionally Crysis, specs are in my sig. I feel like I am vastly underusing this piece of equipment, and would like to use some of the untapped hard drive space and processing power to give me some added value in my TV-viewing. How do I go about using the hard drive space on my PC to augment my DVR cable boxes and give my TV access to online content? I already am using both of my video card's outputs for my two monitors. I can upgrade the PC if necessary (additional ram, SLI video card, more hard drive space, whatever) but would prefer not to. In my home i have 3 DVR cable boxes from Comcast, each is a dual tuner and rarely is more than one in use at a time. One thing I would like to do is allow each of my TVs to 'see' the DVRs from the other rooms, but my primary goal is to increase my total recordable space (120 gb isn't a lot especially in HD; I've got most of my 750 gb HD unused and can allocate a fair portion of it for this purpose). What can I do?
