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 on the network decodes it, where encoding and decoding is done on the card. I want to find the latency of the card before buying it. > > Check the IVTV list for the latest info. Thanks. > > Dave Sandeep >
