The ReplayTV community is very active and there are some very talented programmers developing tools for use wiht Replay units. I'll have to say that the toolsets are much more polished and easier to use than those for the Tivo.

Welcome to the ReplayTV Hacking Project!

Bean bags are great for home theaters for extra seating on the floor especially for kids. Here's a great web site with some really first class bean bags to match any home theater decor....
These are pretty pricey so of course you could get a faux leather one at Target for $19.99...

This is a really great deal for those looking to play around with a PVR for the first time or for a Tivo user that wants to see how the other half lives with ReplayTV. Do some web searching for an online coupon for ReplayTV and you can get as much as 15% off this price.

Some cool things abour ReplayTV is that it has ethernet capability native in the unit and there are some really great tools out there for extracting and streaming your shows from a Replay. Also, for those into home theater, the Replay 5000 series has a component video output that outputs a 480 line progressive (480p) output.

Just picked up this software for $50... Since I already had a TV Tuner card and a remote, I thought I'd give it a try. It is too early to say if this really turns you HTPC into a Tivo, but it looks promising. Remote access to the system to setup recording is a real plus. Check it out...
