	You have 0.0 clue. Go crawl back under your rock.

	We talking PC's vs. Tivos here. The sloppy seconds you
get at Computer Reniasance are going to be better spec'ed than 
even a new Tivo.

	The series 1's only had 100mhz cpus.

	Pricewatch says differently.

	A 486 can decode mp3.

	...and we're once again back to the meagre hardware of the
real tivos that don't have a problem with this sort of thing either.

	Oh puleeeze.
