Snapstream introduces PVR for your desktop

Moving a step closer to convergence of TV and Computing, Snapstream offers all the power of digital video recording but without the cost of more hardware or monthly fees.

It also has the built in advantage of being able to convert recorded shows directly to both MPEG 2 and DivX formats, a built-in streaming video server routes live or recorded TV to any computer connected to your home network, or even stream recorded shows to you ANYWHERE IN THE WORLD via across the Internet using a broadband connection! Users can also make changes to recording via the internet.

Good enough for me!
