878tv on Mandrake 9.1

[Mattia Martinello <liste@xxxxxxxxxxxxxxxxxxxx>]

Hi,
I own a 878tv TV card, rev. 3F and I am trying to get it working on 
Linux Mandrake 9.1.
The DrakeTV application recognises a "Brooktree bt878" card with a 
Philips tuner.
There are not error messages, but when I try to watch TV with XawTV I 
don't see anything. If I try to search the available channels the 
program doesn't found anything.

What can I try to get the card working?

Thank you very much
Bye
Mattia.
