hi,

thanks for the info. I agree that in ubuntu there seem always to be 
"unfinished" things and then rush many things into "stable" releases 
when "it's time".

Anyway....

i tried to upgrade the system from "hardy" to "intrepid", which meant a 
lot of ports upgraded, including kernel
2.6.27.9.13

that thing you say...

"All saa7134 DVB-S drivers have this option as diseqc = 0 in the config

currently and it should be right for the Trio too and the isl6421 should
forward."


is there any way i can try this? is there any config file i can edit to 
make that happen (to make diseqc work)?

i'm not a experienced user ,but i've got the card and i'm really willing 
to help in any posible way.

just let me know what i can do.

thanks.
