Sorry, I don't have any links to sites for that kind of stuff.

I just looked briefly at the Osprey cards, and didn't really see anything implying any kind of low level access like the simple cat device> file.ext stuff that the PVR-x50's allow. That's not to say that it won't work though, if it's a linux device, it's entirely possible that you can just cat the device and pipe it to the capture file. I am not familiar with those cards, however, so your mileage may indeed vary.

In my (somewhat limited) experience with consumer-grade video capture, software compression is evil, and multiple streams will make you wish you had hardware compression, but I do not know what your intentions are with the resulting stream. FFMPEG certainly works, but you better have some serious processor power to keep up if you're doing realtime and multiple streams.

Good luck!
