Please use the following options with care as deselection of drivers which are in fact necessary
may result in DVB devices that cannot be tuned due to lack of driver support:
You can save RAM by deselecting every frontend module that your DVB card does not need.
First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling:
d.) "Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
=> "DVB for Linux" "DVB Core Support" "Load and attach frontend modules as needed"
If you know the frontend driver that your card needs please enable:
e.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
=> "DVB for Linux" "DVB Core Support" "Customise DVB Frontends" => "Customise the frontend modules to build"
Then please select your card-specific frontend module.
2) Loading Modules
==================
In default cases bttv is loaded automatically.
To load the backend either place dvb-bt8xx in etc/modules, or apply manually:
$ modprobe dvb-bt8xx
All frontends will be loaded automatically.
Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
Exceptions are:
- Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom.
People running udev please see Documentation/dvb/udev.txt.
