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

Hello

Try with + 166000 Hz if you are in france

Hi,

I made a success of with scan the channels with a vanilla Linux kernel 2.6.18 and the master v4l-dvb development repository (downloaded the 28/11/2006). I did not need to use kradio before. :o)

The firmware loaded correctly :

The problem came from the initial scan file fr-Vannes. I tested all the files for France with this script:

#! /bin/bash
for t in /usr/share/doc/dvb-utils/examples/scan/dvb-t/fr-*; do
   /usr/bin/scan $t
done

And, I found two frequencies which run :
- fr-Orleans : 674166000
- fr-Toulouse : 698167000

There are two problems in the file fr-Vannes, the frequency can be shifted of 166000 or 167000 and especially the value of the "guard-interval" must be "1/32" and not "1/8".

I will search which is best shift 166000 or 167000, and I will post the good file.


Regards.
