[AG-TECH] Multi-channel video capture

Did anybody every resolve this topic for the perfect quad-input video
capture card? I am about to build another three CPU ag node and would
really like to use a card such as the winnov videum 4400 quad input
video card or Ituner Spectra 8 video capture card due to my lack of PCI
slots.
I really need a card that performs seamlessly with AG 2.x and ideally
would like one that still works with AG 1.x.
Any suggestions would be great.
