Default Looking for a card that can decode 1080i VC-1 w/ temporal spatial deinterlacing

Hi

I'm sorry if this has been explained somewhere - I haven't been able to find it.

I'm looking for the perfect card/chip for VDPAU decoding. I would like to future-proof, so I've been looking at G98 based cards (for their VC-1 decoding capabilities) with 512MB memory to avoid problems with advanced profiles. G98 based cards are however all low-budget cards, that can't do temporal spatial deinterlacing on 1080i content.

This has of course changed with 180.35, since all cards now can do VC-1 decoding. My questions is thus the following two:

1) How has VC-1 decoding capability been acomplished on all cards that didn't support it previously? I assume it's a mixed HW/SW decoding process, but what are the CPU requirements for say decoding a VC-1 1080i/p bluray movie? (I guess it could perhaps also have been acomplished using shaders for the parts that are missing on non-G98 cards.)

2) What cards will be able to do temporal spatial deinterlacing on 1080i content (on all formats; h264, VC-1, MPEG2)?

Furthermore I assume that at least 512MB memory is the best way to avoid problems with advanced profiles while still being able to use fancy desktop themes and effects.

Thanks in advance.

I'm looking forward to getting a capable NVIDIA card and BluRay drive to fully enjoy my 40" 1080p LCD TV.

You should know that playing encrypted blu-ray disks is still far from easy on linux.

As I wrote, I like to ready for the future, since I'm sure it will be possible (if it isn't already) to play BluRay discs without too much hassle in the near future.

This link is definately a good start.

*bump*

I'm amazed that noone feels like commenting on this...

Somebody has to have at least an idea about what cards are capable of decoding VC-1/h264 and doing temporal spatial deinterlacing on 1080i material.
