hi, I have the same problem like Halim Sahin with his tt dvb-c 2.1 the card works fine with qam64 channels channels with higher modulation like qam256 produce several dropouts I already tried to change the PWM in ves1820.c - with no effect according the ves1820 spec the frontend should support qam256 so, it looks like a linux driver problem any ideas how to fix it? thanks marco _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
