The search engine seems to be down, so I did some searching on the AVSforum. The "definitive guide" recommends GeForce cards, but then I've found several threads where people say their GeForce cards either flat out won't do 1080i or they just output a doubling of 540p (so you get line 1 twice, line 2 twice, and so on; no interpolation): thread 1 thread 2 thread 3 Right now, I've got my old 3dfx Voodoo 5 5500 in my HTPC. It'll do 540p just fine, but I really want to try 1080i. I can't get it to do an interlaced signal with powerstrip, but then maybe I'm just a retard and don't know how to set up the software. I'm willing to get a new video card for the job, but I definitely want to know that the card I buy will do 1080i before I lay down the green I have an opportunity to buy an old geforce 2 TI 64MB card for pretty cheap, so I'm trying to figure out if that card will work ... otherwise it's back to finding a new retail card. Any help?
