hello,

i'm still having problems with my KNC 1 DVB-C card using a CAM. 

While using the card without the CAM plugged in I can watch all unscrambled 
channels perfectly. But when I plug in my Alphacrypt Light Cam there is no 
data coming out of /dev/dvb/adapter0/dvr0 using czap -r.

'modprobe budget-av' without the CAM and using 'czap -r ZDF' has following 
output:
status 1f | signal 8a8a | snr f1f1 | ber 00195000 | unc 00000000 | FE_HAS_LOCK

and doing 'cat /dev/dvb/adapter0/dvr0 > /tmp/test' will fill the file with 
data 

plugging in the CAM and doing 'czap -r ZDF'  again will output nearly the 
same, except the ber value is now lower:
status 1f | signal 8a8a | snr f1f1 | ber 00029a90 | unc 00000000 | FE_HAS_LOCK

and doing 'cat /dev/dvb/adapter0/dvr0 > /tmp/test'  creates the file without 
filling it with any data

even removing now the CAM doesn't change anything
status 1f | signal 8a8a | snr f1f1 | ber 00029a90 | unc 00000000 | FE_HAS_LOCK

but when I doing rmmod budget-av & modprobe budget-av everything works for the 
unscrambled channels perfectly

nw
