Hello, I have a problem with the KWorld USB Dual DVB-T TV Stick (DVB-T
399U): http://www.linuxtv.org/wiki/index.php/KWorld_USB_Dual_DVB-T_TV_Stick_(DVB-T_399U)

I am using it on MythTV with Debian Squeeze (2.6.32). It is a dual
device, sometimes the second adapter works great, but sometimes has a
pixeled images. The first adapter always has pixeled images, I don't
know how to describe the pixeled images, so here is a mobile record:
http://dl.dropbox.com/u/1541853/kworld.3gp

I have this firmware:
http://palosaari.fi/linux/v4l-dvb/firmware/af9015/5.1.0.0/dvb-usb-af9015.fw

I read on the linuxtv wiki and there are some problems with dual mode,
there is some links for how to patch the similar driver (Afatech/ITE
IT9135), but I am not good enough to understand the code.

I check the kernel messages:

Aug 15 13:53:58 htpc kernel: [ 516.285369] af9013: I2C read failed reg:d2e6
Aug 15 13:54:29 htpc kernel: [ 547.407504] af9013: I2C read failed reg:d330
Aug 15 13:54:44 htpc kernel: [ 561.902710] af9013: I2C read failed reg:d2e6

It looks I2C problem, but I don't know how to debug it deeper.

I don't know if this is important, but I compile the s2-liplianin for
other devices this way:

apt-get install linux-headers-`uname -r` build-essential
mkdir /usr/local/src/dvb
cd /usr/local/src/dvb
wget http://mercurial.intuxication.org/hg/s2-liplianin/archive/tip.zip
unzip s2-liplianin-0b7d3cc65161.zip
cd s2-liplianin-0b7d3cc65161
make CONFIG_DVB_FIREDTV:=n
make install

Can you help with this? This hardware is a very cheap and works well
for HD channels but, I don't know why sometimes has pixeled images.

Thanks for your help, best regards.

Thanks Jose Alberto, I search on google for pid filters but I don't

How can I limit bandwidth on dvb?

If the driver has pid filters you can enable it with the parameter=20
force_pid_filter_usage=3D1 of dvb-usb.

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.
