Nat - I think he is asking does it work/compadable with Vegas... I'm pretty sure the answer is NO - Vegas doesn't send preview out through the Parhelia to NTSC monitor.
Unfortunately, you can't. NTSC output from Vegas is firewire only. It's one of the very few problems that I think Vegas has. And unfortunately for all the professional tools that Vegas offers, I think that is a significant detriment to the program's acceptance in the "pro" world.
SoFo, what are the chances of getting full support for this fine card? I was looking at it for a purchase in a few months, and am disappointed that such a good card isn't supported fully.
i use one and they are great but the color from the graphic card may be slightly different that what is out of the DV and printed to tape .. a drawback to using the NTSC monitor out on the card (if you could) ... you can do this with other apps -- but i dont for this reason ..
