[mythtv] problem with Avermedia DVB-T 771 under kubuntu 6.06

[philippe]

Hello,

I need some help to find the reason that my DVB-T Avermedia card is no more 
reconized from mythbackend under an installation of kubuntu 6.06 (kernel 
2.6.15.26).

My previous installation under mdk2006 worked but now when I try to add a DVB 
card with mythtv-setup, I have a "could not open card#0" on the frontend 
device line (same result with card#1 to 7).
The strange thing is that the card seems to be initialized, look at this logs:
