Compiling v4l DVB drivers for SAA7134 and XC2028

Use mercurial to checkout the latest driver code. Compile the code against the current kernel (2.6.24.3-34.fc8), and then install the modules.

hg clone http://linuxtv.org/hg/v4l-dvb/
cd v4l-dvb
make
make install

Note: If moving from the v4l-dvb-experimental tree, the E506R card has changed to card 136 (AVerMedia Cardbus TV/Radio (E506R)), and the tuner has stayed at 71 (Xceive xc2028/xc3028 tuner). Given that I have hard code the card and tuner id's into the modprobe.conf, this must be changed.

The v4l-dvb driver requires the firmware 'xc3028-v27.fw'. To generate this file, follow the instructions in the file 'linux/Documentation/video4linux/extract_xc3028.pl' [2]. This will result in a firmware file, which must be copied to '/lib/firmware'.

#
# AVerMedia M103-C Hybrid MiniPCI module. Card 136 is an
# AVerMedia cardbus E506R, but it has an XC30x8 tunner and
# MT253 demodulator. Tuner 71 is the Xceive XC3028 tuner
# driver, which also supports the XC3018 tuner.

# 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
#       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) run the script:
#               ./extract_xc3028.pl
#       4) copy the generated file:
#               cp xc3028-v27.fw /lib/firmware
