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.
+If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
People running udev please see Documentation/dvb/udev.txt.
In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
