Well, if you wanted to bring this up, the forums over at pchdtv.com
would be the place, I would think.
Indeed I think the driver might stand a better chance of being
incorporated into the mainstream kernel if it fit into the (newer) DVB
driver infrastructure. On the other hand, then what would you do with
the NTSC-tuner half of the card? Or does DVB have a provision for an
uncompressed video stream?

Ah, you're right, sorry ... I was remembering the MGT (in PSIP) that
has all this info in one place.
