	Exactly. All the cards have the same PCI ID, except for one DST-MOT card i 
had. The dst_check_ci () in dst.c detects the card types.

	If you see this log, bttv says i have a terrestrial card, but the dst 
frontend driver reports it correctly.

	If you need, i can send you the manufacturer's driver source for 
kernel-2.4.20 (?) (Redhat 9). I have to search it out on my network, just 
give me a little time for that.
