I made more tests today with my KNC1 DVB-T card on a Debian sarge machine. With the CVS DVB drivers on a 2.6.11.4 kernel, I have : Mar 18 19:35:45 localhost kernel: Linux video capture interface: v1.00 Mar 18 19:35:45 localhost kernel: saa7146: register extension 'budget dvb /w video in'.

Mar 18 19:47:02 localhost kernel: tda1004x: waiting for firmware upload... Then no other message. So : - with the CVS drivers, the firmware can't be uploaded ; - with the DVB drivers in 2.6.11.4, the firmware is uploaded OK but the card doesn't work :-( Any other experience ? -- Alexis
