I just upgraded my HTPC from an AMD64 3000+, with an ATI x800Pro to an AMD64 4600+ with an Nvidia 7800 GT. Both are displaying video over component out, but while the ATI card never had any problems, the nvidia 7800 Gt, is droping about 20% of all frames, the product works great on the LCD screen that is the primary (or secondary display), but drops frame instantly upon being run on the HTPC over component Video. The problem seems to be limited to VMR9, as overlay seems to work, but I do not want to use overlay, so that not a solution. During all this the CPU does not exceed 45%, so its not a CPU issue, and as I said ZP displays without a hitch on the LCd, but the TV drops frames like made, so my question is why and what can I do about it as this make the new HTPC unusable. I've never heard of such an issue with Nvidia cards before (by the way the overscan reduction is great on Nvidia and HDTV output was much easiler than the ATI card. and of coure I'm running 77.77 as these are the only drivers to support the 7800 GT).
