Hi all,
answering to myself... I upgraded to the latest cvs version of the DVB
driver, and everything seems to work well, now.
Thanks to whoever fixed the problem!!!
I also tried the latest cvs version of the dvb-kernel driver, and it
correctly locks the signal. However, if I use mplayer to play the
channel, it blocks after few seconds (using the DVB driver, mplayer
works well).
Thanks,
Luca
