Nice overview! although I think a savvy person can build a pretty awesome MythTV box for much less. shrug I figured around 600 dollars all told for the one I have planned (including shipping) although I’m a very careful frugal shopper (ok I’m cheap as hell)
while I’m here… cheap plug =P I just started a community dedicated to this idea: Build Your Own PVR
(ironically I own a tivo)
