KNC1 tv station dvb-t tuning problem

Hi,

I have a strange problem with this card.
generally it works, but tuning on channel 40 (626000000) does not work.
other channels work fine. I tried the original drivers provided by kernel
2.6.24.5 and cvs updates. (also tried with my old kernel 2.6.18 and cvs updates,
always with the same result).

I use the frimware tda10046 from get_dvb_firmware script (TT_PCI_2.19h_28_11_2006.zip)
tested also the frimware from  "TT_PCI_2.17", but I think this is the same firmware.

dmesg reports firmware revision 20.

so now the strange thing: If I first start windows, and using globetv, I have all channels.
then, doing a warm start loading linux, dmesg reports version 26 (think this is the
firmware from windows globetv) and tzap works on channel 40.

what's the problem?
