I don't know if I mentioned it previously, but the DVR8082 card definitely doesn't support audio. I route my audio to my TVs anyway from the cameras, so it saves me another RCA splitter. I still wouldn't recommend the software, as I recall they come with pico2000.
If you don't need more than four channels, even taking into account future growth, than I'd find a four channel card with 120fps. I know my search was difficult, but that was primarily because I was trying to find a PCI 2.2 card that would work in my first Dell. I bought this one thinking it was a universal PCI card (because of notch in front and back), but it wasn't, so instead of continuing my search I bought another $300 Dell Server with PCI 2.1 and rearranged my setup.
