Hello,

I finally found that unplugging and plugging my pci card suppresses
the kernel errors.

However, I didn't find any channels with an initial tuning file for my
cable provider in France so I tried w_scan and it didn't find anything
either.
$ w_scan -fc
w_scan version 20080105
Info: using DVB adapter auto detection.
   Found DVB-C frontend. Using adapter /dev/dvb/adapter0/frontend0
-_-_-_-_ Getting frontend capabilities-_-_-_-_
frontend Philips TDA10023 DVB-C supports
INVERSION_AUTO
QAM_AUTO not supported, trying QAM_64 and QAM_256.
FEC_AUTO
-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_
50500:
[.....]
858000:
ERROR: Sorry - i couldn't get any working frequency/transponder
 Nothing to scan!!
dumping lists (0 services)
Done.

Under windows, the program shipped with my card found 85 channels and it works.

what's wrong ? please help !
Guillaume
