I wonder whether it might be possible to use a more eonomical card which is only powerful enough to decode 1080i without deinterlacing it and take advantage of the abundant CPU power most people have nowadays to perform software deinterlacing. It may not be possible to have something as sophisticated as NVidia's temporal + spatial, but some of the existing software filters should scale up to HD without overloading the CPU seeing as it wouldn't be doing the decoding too.
Well, you can get a gt220 for around $40USD which does full rate temporal-spatial 1080i and allows you to use it with an old slow cpu's that are dirt cheap if you don't already have one collecting dust in your basement. Not sure how much more economical you can get aside of free.
