I am a Tivo user currently (trying) to get on the Myth roll.

The digital tivos (currently just the direcTV integrated ones) are 
somewhat like a HDTV myth system in that they capture the incoming
stream directly, so no quality loss at all.

But the standalones have a quality loss, for sure.  It is noticeable
if you look closely, but it doesn't scream at me.  The quality seems to
my eye to be slightly better out of the Tivo encoders than I have seen 
on PC-based TV capture/encode systems, but I haven't done a comprehensive
survey.  With some hackery, you can change the encoding settings on the 
tivos beyond the built-in options, which also may have given the tivos an
edge in my personal comparisons.
