PVR Software for the PC

PVR Software for the PC, SageTV and SageRecorder Let You Pause Live TV, Instant Replay and Record Your Favorite TV Shows

We have a ReplayTV that I really, really like. I have also experimented with an ATI TV card that works well, but the TV guide software is 'marginal' and I don't want to spend the time to configure a turnkey solution and have a PC sitting beside my TV in our family room.
This is an interesting alternative that I will look at later.
