I have a 4080. I was going to add another 80G, but I found I didn’t need it (yet). REPLAYTV has revolutionized the way i watch tv. Sort of like the empeg changed my listening. I have never used a TIVO, so i cant compare it.

I REALLY like the automatic commercial skip and the ability to get shows from planetreplay.com if i have a recording conflict.

There is a pretty good size hacker community at http://www.avsforum.com/avs-vb/ that have come up with some very helpful tools. The ability to send and receive shows to my pc for one.

I havnt had to deal with tech support, setup was a breeze. But I hear that its traditional sonic blue.

Warning: Once you get one, its hard to go back to live tv.
