Thanx! Now it works!!

Watching some Danish (Dansk) channel, about Napoleon.

Thanx again, for mocking me up.. It was the channel.conf, that was wrong

The channel.conf -file that I used before, was 6 month old and from my 
previous computer.
(Now "dvbscan" doesn't detect anything on that bandwidth. And that "TV6" 
was on that..

If I run dvdscan against the closest mayor city (Malmö in my case, here 
in south Sweden), it only tunedin encrypted channels. BUT, against  all 
of Denmark (file "dk-All") I get a some..

Its strange though.. I CAN SEE "TV6" unencrypted, but in Windows XP. But 
there with A program called "PowerCinema" is used (in XP OS).
(tuning is a fuzz there also, I believe "PowerCinema" download channels 
and guides and what, from the internet. It would maybe be a point to 
retrieve its (channel) configure file. I have looked, but found none.

Another question now, how is all these "initial-tuning-data" created??

Can I compose one, of these by myself (from other nearby citys), or how?

There is a deb-package called "mercurial".
(I suspect it doesnt have anything, todo with this, no?)

I used the linux-kernels-source. in its documents for this. Downloaded 
the firmware..
(I include dmesg output in the end of this email, anyway. The revision 
is 20, and not a LifeView fabrication..

Yes, now my system is relatively fresh, again (I dont load any 
kernel-module with any extra options).

I also tried to compile the kernel (there was this option there 
VIDEO_ADV_DEBUG). But unfortunately I cut away so other stuff, soo the 
new kernel got panic at bootup. Another story..

It was the "channel.conf" that was wrong.. Thx again!
(what a fuzz)
