I was thinking something more in the price range and size of a VCR, not a whole blown computer, which is easily $1,000 when all is said and done.DVRs I would not count as you have no way to archive stuff, it's stuck inside the box and once it's full it's full.
It takes a little thinkery and research but you CAN offload recorded video from a TiVO. It's not even hard, there's a Java program to help you do it.
