Hmm. Yeah. Rereading it now does make a lot more sense. Oh well

If you're interested in making a TiVo style thing with a massive NAS somewhere then it's probably cheaper to just build it yourself from other parts. A fanless VIA EPIA board, Hauppauge PVR 350 card for hardware MPEG + TV out and something like MythTV to run it all. You can have many clients all running off a single server and multiple tuners as well.
