Hi, thanks again for the help you are offering me.

However, i haven't been able to get diseqc working and i don't think i 
will....

let's go through all the thing...

i've got a lifeview flydvb pci trio card (saa7134) which has different 
chips, to tune satellite, digital terrestrial tv and also radio.

i used to have this card running in a dual boot with windows xp, where 
everything worked like a charm, and another one where i kept installing 
linux distros without any luck until "kubuntu hardy" came out. At that 
point, as the card with diseqc worked "out of the box", i decided to 
erase all data and move to ubuntu.

then i upgraded the system and also moved the tower from its place to 
next to the tv (to be a medicenter computer :) ). Then i couldn't view 
the channels anymore. I tried to retune with no luck... I check all the 
cables, just in case one of them was in bad shape. I even replaced the T 
connectors, just in case.

Then is when i first posted here with all my diseqc problems.

Since that moment i've reinstalled the whole system several times and 
even compiled the latest linux-dvb modules, but no matter what i do... i 
can only tune what is on switch 1 of my diseqc, never switch 2.

so... is it possible that somehow i've broken the card someone? the 
truth is that what used to work in windows... doesn't work anymore... 
this evening i went back to windows just to check if the card, the 
diseqc and everything was fine... and i had so many problems to get the 
satellite working as before. i used to use progdvb, which supported 
diseqc for my card and now it just can't tune through diseqc, none of 
the two satellites. other software does know how to get through diseqc, 
but only switch 1.

is it then possible that it's "half-broken"? i mean.. it's still able to 
tune, but not through diseqc because.....................

i'm no satellite or linux expert, but now i can confirm that while i 
still can view satellite channels in windows, it's not working as it 
used to anymore...

i've checked cables and i don't think it's an issue from the diseq 
thing, cause i've got two and both give the same problem.

well.. i guess i won't be able to use diseqc anymore... but if only 
someone could through some light on this...... at least how come i've 
broken it...

thanks.
