I found out a solution for this if anyone also comes across this problem.
It is because there are some kind of conflicts between duplicated
kernel files in /lib/modules/2.6.24-20-generic/empia/ and in
/lib/modules/2.6.24-20-generic/kernel/drivers/media/, I used again the
command in the kernel directory:
ls ../empia/ | while read i; do find . -name $i -exec rm -f {} \; ; done
After three files get removed, the dvb tuning function works again.
Cheers,
Peng
