Hmm if this is your boardhttp://ark.intel.com/products/50369/Intel-Desktop-Board-D945GCNL
it has both PCI and PCIe slots and so factors to take into consideration would be
1. Does you casing limit you to low profile or are normal height expansion cards good to go?
2. What standard of Live TV and/or videos are u wishing to record/capture i.e Analog, DVB-T, DVB-S, cable, etc
3. Do you wish just to view/record one channel or multiple channels?
