Tunerless capture cards?

[bobhaze]

I was wondering if anyone has any recommendations for a good HW capture card without a tuner that is compatible with BTV. Since I use a sat STB as the only source I have no need for a tuner in the PC. I have a PVR250 in the system now, but could use it elsewhere.

I have been considering the Audigy 2 ZS Video Editor, here.
But I would like to be certain that I could use it with BTV before I try it. I'm willing to look at other options too, but I could use the sound card as well for its ability to decode Dolby Digital from the external input from the Satellite receiver. It looks like a one box solution to two needs.
