I'm pretty sure that all their doing is a trick. Something I've though about doing, as well... just with regular video cards. The R/G/B outputs on the vid cards aren't that special... they can output any data you want. If you get one that can add a composite sync pulse (e.g. "sync-on-green capable), you'd be set to output component straight off the card. Put Y data (with CSYNC) out the G DAC, and Pb/Pr out the other two. Then you'd just need to trick the card into *NOT* doing a colorspace rotation. Something like a phony Xv type like YUY2 UYVY YV12 I420, etc... just no transformation.Seems ATI sells a DVI->component converter for their 8500 and 9xxx cards for $29. Perhaps that is the way to go. That should work with an SDTV with component video connections no? Maybe cheaper than the cheapest vidcard you would want to buy and then an additional U$129 for the Audio whatsitcalled thingy I posted about earlier.
I'm pretty sure that's what ATI's doing, and I'm also pretty sure it's a winders driver only thing.
