Re: Afatech AF9013

Thanks again, I edit /etc/modprobe.d/options.conf

options dvb_usb_af9015 adapter_nr=3D4,5
options dvb-usb disable_rc_polling=3D1
options dvb-usb force_pid_filter_usage=3D1

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.
