Hi again,

and thanks for the info.

Unfortunately, diseqc seems broken, because no matter what i try

-s 0, 1 , 2 ,3.... i get 28.2E signal

however, 4 shows an error, as you said.

It used to work... so i'll try to get back or compile new linux-dvb 
module as you suggested.

i'm really really newbie in this, i'm using kubuntu, so imagine.... 

i don't even know how to get started, i barely install thing by "apt-get"

i'll try to find the way or post instead my problem in an ubuntu forum.

thanks for the info.
