The KWorld/V-Stream XPert DVB-T PCI card and Linux

THIS INFORMATION IS OBSOLETE

This information is no longer current and is only kept for historical purposes. Support for the KWorld DVB-T cards has been integrated into the Linux kernel as of version 2.6.13, and it no longer works as described below. Current information is available at www.linuxtv.org .

The KWorld/V-Stream XPert DVB-T PCI card now works with Linux. To my knowledge there are three versions of this card, the first has a Samsung tuner which is similar to the DNTV DVB-T card, the second has a Thompson tuner and is similar to the Hauppauge Nova-T model 90002, and the third has a different Thompson tuner. The first two cards are supported (and possibly the third too). To get the Hauppauge style card to work, look for instructions to get a Hauppauge Nova-T model 90002 to work. These instructions can be found on the web.

On this page I cover how to get the KWorld card with the Samsung tuner to work.

• Download the driver package from here.
• Extract the archive somewhere.
• Edit the files DVB-Build.sh and DVB-init.sh changing the value of BUILDDIR to where you extracted this archive.
• Run "DVB-Build.sh clean"
• Run "DVB-Build.sh" this should build the drivers for your kernel.
• To start the drivers run "DVB-Init.sh start".

If this is the first time you're using a DVB card, you'll need a channels.conf. You'll need to do the following to create one:

• Download the dvb-apps package from here.
• Extract the archive somewhere.
• cd dvb-apps/util/scan
• make
• dvbscan dvb-t/your transmitter > channels.conf
  e.g. dvbscan dvb-t/uk-CrystalPalace > channels.conf
• Copy channels.conf to ~/.tzap, and ~/.mplayer if you intend to use mplayer.

With SuSE 9.3 using kernel 2.6.11, you can get this card to work with the default kernel using the following:

#!/bin/sh
modprobe firmware_class
modprobe video-buf
modprobe btcx-risc
modprobe i2c-core
modprobe v4l2-common
modprobe v4l1-compat
modprobe i2c-algo-bit
modprobe videodev
modprobe ir-common
modprobe tveeprom

modprobe dvb-core dvb_shutdown_timeout=0
modprobe dvb-pll

modprobe mt352
modprobe or51132
#modprobe or51211
modprobe cx22702

modprobe video-buf-dvb

modprobe saa7134
modprobe saa7134-empress
#modprobe saa7134-dvb
modprobe cx88xx
modprobe cx8800
modprobe cx8802
modprobe cx88-dvb

PCB has DVB-T PCI... written on there but it's not clear from the picture and I'm not taking the board out again.
