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.

Thanks both!

I don't know how wide is the stream, but it could be a USB wide
limitation. My board is a little ION based and I have some USB
devices:

$ lsusb

Bus 001 Device 002: ID 1b80:e399 Afatech
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The problematic twin device is the "Afatech" one, there is an DVB-S2
USB tuner, a bluetooth dongle, a IR receiver and a wireless
mouse/keybord receiver.

Now I am at work, I will try to disconnect all devices and try with
just the DVB-T device.

I use to try with MythTV if it works or not. Is there any other tool
to test and debug more deep about USB or DVB wide?

I apreciate your help. Thanks and best regards.
