Home Media Center Dilemma

I previously posted about possibly using an XBox with XBox media center on it, or building a Linux box to use MythTV on. Well, I decided that the primary feature that I want is the ability to record television. AFAIK, this is not possible using XBMC so that option is out. Also, the price of building a Linux box for MythTV will be far greater than if I were to just get a PVR from my television provider. Not the nerdiest solution but maybe I can hack up the PVR...
