I found this new startup site that may prove to be very interesting! It is CozmoTV.
From the site...
"CozmoTV enables you to easily find any cable or satellite content and schedule it for recording on your TiVo. Over the coming months we will be adding the ability to record Internet video on your TiVo and other devices such as Media Center PCs, PSPs, iPods and standard Macs/PCs."
