device number != card number

Device number is a number used by the kernel to access the device.  Card 
number is used by Myth to associate settings with devices.

card number = cardid

cardid is a sequence number assigned by MySQL (autoincrement).  That 
means that you probably set up and deleted quite a few cards to get your 
HD-3000 working...

Good you didn't try.  It wouldn't have "reset" your cardid's--would have 
actually caused 33, 34, and 35 if you had deleted your originals or, if 
you left your PVR-x50's and deleted the HD-3000, the 3000 would have 
become 33 (giving you 1, 2, and 33).
