Hi,
I have a DVB-T card ASUSTeK P7131 Dual, and I use a vanilla Linux kernel
2.6.18 with the master v4l-dvb development repository (downloaded the
28/11/2006).
I can scan and to listen a radios with Kradio, but I don't scan the
DVB-T channels.
I load the modules with :
- modprobe saa7134-dvb
- modprobe saa7134-alsa
The dmesg is:

For the scan of DVB-T channels I use the file of the dvb-utils package
fr-Vannes :
# Vannes - France
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 674000000 8MHz 2/3 NONE QAM64 8k 1/8 NONE

T 818000000 8MHz 2/3 NONE QAM64 8k 1/8 NONE
And I have this result:

I also tested with the file modified according to the trick of Hermann
Pitton (add a positive offset of 167000Hz) :
# Vannes - France
