Hello,

Thanks for your reply! :)
My dish is well aligned. I have about 70-80% signal level on most  
channels...
The problem about "no data" in /dev/dvb/adapter0/dvr0 is very weird...
I got the CVS from linuxtv and the problem seems to have reduced, but it  
still happens...
This is the situation:
I szap into a channel, it displays "locked", I do: cat  
/dev/dvb/adapter0/dvr0 and there's data comming through.
I stop szap, and restart it again... same channel or another one... it  
locks again and there's data on dvr0..
stop szap, restart it again, and it doesn't lock!!! or even worse.. it  
locks, but there's no data comming out of dvr0!!!
Sometimes if I remove the modules, reinstall them again, and restart szap,  
it resumes working...
and end up failing some time later...
All this would make me think that the card is defective, but I never got  
these problems under WinXP...

Weird! hum!

btw, can you see a list of the dvb-s channels (in mplayer) in the OSD menu?

thanks,
gb
