Yup, I thought as much.

Are you able to run the card under windows? If so, can you tune it to a DVB 
station using the windows software, and then run saa7146dump from:

http://www.linuxtv.org/downloads/saa7146dump-0.1.zip

For your card it would be:

saa7146dump 0x1894 0x0011 0x68 0

It won't work on XP SP2 sorry :( I must fix that sometime.

This will generate a dump of all the card hardware registers - post it here so 
we can see how they're setting it up.
