By "passthrough", do u mean "no Mpeg compression /decompression"?
well, I actually want it, because what I want to implement is a streaming 
real-time application, where 1 machine encodes live mpeg video, streams it over 
the network and the other machine decodes it, where encoding and decoding is 
done in the card. So, I want to find the latency before actually buying the 
card.

I will check this list also. Thanks.
