Thanks again, I edit /etc/modprobe.d/options.conf options dvb_usb_af9015 adapter_nr=4,5 options dvb-usb disable_rc_polling=1 options dvb-usb force_pid_filter_usage=1 I change the signal timeout and tuning timeout and now it works perfect! I can watch two HD channels, thanks for your help. I really don't understand what force_pid_filter_usage do on the module, is there any documentation? Thanks and best regards. 2011/8/16 Jose Alberto Reguero <jareguero@xxxxxxxxxxxxxx>: > On Martes, 16 de Agosto de 2011 00:22:05 Josu Lazkano escribió: >> 2011/8/16 Jose Alberto Reguero <jareguero@xxxxxxxxxxxxxx>: >> > I have problems with a dual usb tuner.
