Once again, someone is coming out with PVR stuff for personal computers. This time for the mac. The first I read up on was EyeTV. This one looks interesting, but it's only for watching TV on your computer. Also, it suffers from not being able to control a cable box remotely. This is one of the biggest shortcomings of something like this. The second being how much it will effect machine performance. What I love about the TiVo is that I never have to worry about any other process slowing it down, or having to turn it off because it isn't letting me do something else on my computer. To me, this is the big benefit of things like TiVo and Replay.
