I just finished testing those ones and they seem to fix my specific issue.

There is still one thing that puzzles me, but maybe it´s just my
misunderstanding on how dvb-t protocol works.

In my dk file I only specify:

because for simple testing I don´t need to scan the whole spectrum.

Now, in some versions of the driver, it automatically picks up 730MHz (I
know it´s a good frequency in the area as I get it at my home and shares
the same channels as 586).

What I noticed is that sometimes it tunes and time outs, sometime it
tunes and scan correctly, but with the latest driver from HEAD, it
failed completely to tune with the usual error.
Not sure if this info might be relevant.

As for analog I am not able to even get scantv to find the channel
broadcasted from the VCR. I´ll need to investigate if it´s a problem
with the VCR/tuner/driver etc. (there is no analog broadcast in dk).

So far this is what I get:

(repeat the above for every single channel and no channels found)

The result is pretty much the same with or without tm6000-dvb loaded.
