Leadtek WinFast DTV2000 H Plus

An hybrid Analog/DVB-T PCI card from Leadtek.

There are 2 versions of this card:

• Device 6f42 [card=51] is the original version and uses the xc4000 chipset. It is not officially supported under Linux. However, an experimental patch with full support (analog TV, DVB-T, radio, and IR) is available at http://istvanv.users.sourceforge.net/v4l/xc4000.html (official support is sitting in staging/for_v3.1 of linuxtv.org's git tree).
• Device 6f44 [card=81] is the newer hardware version that uses an xc3028 chipset which is supported by the linux kernel>=2.6.25 (needs checking). The box of the newer version still reads xc4000 so unfortunately there is no way to know which you are going to get before buying.

Drivers

Device 6f42

As of 26 March 2010, support for this card is not included in the main v4l-dvb tree or the Linux kernel. However, an experimental driver which adds full support is available with firmware at http://istvanv.users.sourceforge.net/v4l/xc4000.html. remember to set the appropriate line in /etc/modprobe.d/modules.conf to be "options xc88xx card=51"

Driver Test Results

• Successful tuning of analog TV (PAL was tested) and FM radio
• Successful tuning of DVB-T has been reported by testers
• Infrared support works

Device 6f44

Card auto detection is terrible at best for these tuners, so remember to configure the module with the correct card type.

# echo "options xc88xx card=81" > /etc/modprobe.d/modules.conf 

After configuring the module you must also extract the firmware for the card.

# In order to use, you need to:
#       1) Download the windows driver with something like:
#               wget http://www.steventoth.net/linux/xc5000/HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip
#               ( find here: http://cdn.pinnaclesys.com/SupportFiles/PCTV%20Drivers/ReadmePCTV.htm )
#       2) Extract the file hcw85bda.sys from the zip into the current dir:
#               unzip -j HVR-12x0-14x0-17x0_1_25_25271_WHQL.zip Driver85/hcw85bda.sys
#       3) Download the extract script
#               wget http://linuxtv.org/hg/v4l-dvb/raw-file/3919b17dc88e/linux/Documentation/video4linux/extract_xc3028.pl
#       3) run the script:
#               perl extract_xc3028.pl
#       4) copy the generated file:
#               sudo cp xc3028-v27.fw /lib/firmware
