Viewcast Osprey 460e - Win7 - record mulitple inputs

Hi,
I'd like to use an Osprey 460e to record 4 inputs simultaneously. The inputs are analog SD. This will be done on a Windows machine.

Any recommendations on a software product? The idea is to record the 4 cameras of a live event and mix the video down with software afterwards.

It appears that there's a product on the Mac side called Movie Record from Softron that does something similar to this ... but like I said, it's for Macs.

Thanks!
