I've had nothing but horrible experience with VIA firewire chipsets. I
know at least two were the 6306 chip, the third I don't know. I
couldn't get any of the three to work well, or consistent. I'd say get
a TI or Aegere based card. I've setup two TI chipset systems that
capture and change channels fine.
Priming is as much a matter of your cable box as anything, but odds
are you'll still need some sort of priming to get things stable.
