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.

For usb devices with usb 2.0 when tunned to a channel there is enought
usb bandwith to deliver the whole transponder. With pid filters they
only deliver the pids needed for the channel. The only limit is that the
pid filters is limited normaly to 32 pids.

May I ask how wide DVB-T streams you have? Here in Finland it is about
22 Mbit/sec and I think two such streams should be too much for one USB
bus. I suspect there is some other bug in back of this.

Here the transport stream is like yours. About 4 Mbit/sec by channel, and 
about 5 channels by transport stream. The problem I have is that when I have 
the two tuners working I have a few packets lost, and I have some TS 
discontinuitys. With pid filters the stream is perfect. Perhaps Josu have 
another problem.

I am certain it is the configuration of the second frontend that ripples
through Afatech devices.

I have only got a single AF9015 device so can't test the dual
configuration.

Does the same problems exist when running the second frontend solo or
dual with the Windows driver?

With the IT1937(aka AF9035) the second frontend appeared not to work at
all in Windows in dual mode.
