Hi everybody,
as my first attempt got wordwrapped according to Andrew, now here is my
second as outline attachment:
subjects:
- rewrote documentation from scratch
- added cross references (=>)
- added a date
- reduced card ID references to ONE proven exception
where card autodetection does not work in all cases
- applied automatic approach for module loading
instead of modprobe statements
- no more endless author list: one author, one date

1) General information
======================
-This class of cards has a bt878a as the PCI interface, and require the bttv driver
-for accessing the i2c bus and the gpio pins of the bt8xx chipset.
-Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
+- the bt878a chip is the interface
+- the bttv driver accesses the i2c bus and the gpio pins of the bt8xx chipset
+- card types? => Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge
+- creating device nodes? => Documentation/dvb/udev.txt
-
-Compiling kernel please enable:
+- compile kernel:
a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "BT848 Video For Linux"
b.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
- => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
+ => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
2) Loading Modules
==================
-In default cases bttv is loaded automatically.
-To load the backend either place dvb-bt8xx in etc/modules, or apply manually:
+- default cases: bttv and all frontends are loaded automatically
+- add to etc/modules: dvb-bt8xx
- $ modprobe dvb-bt8xx
-
-All frontends 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:

-2a) Running TwinHan and Clones
-------------------------------
+Exception:
+----------
+- TwinHan and Clones: overriding autodetection might be necessary
+
+a) standalone:
-
- $ modprobe bttv card=113
- $ modprobe dvb-bt8xx
- $ modprobe dst
+- add to etc/modules: dvb-bt8xx
+ dst
+- add to etc/modules.conf or etc/modprobe.conf: options bttv card=113
+- optionally add to etc/modules.conf or etc/modprobe.conf: options dst verbose=(1-4) dst_addons=0x20
+- verbose=1: only error messages, 2: notifications, 3: other messages, 4: debug setting
+- dst_addons=0x20: card owns conditional access slot for scrambled channels
-
-Useful parameters for verbosity level and debugging the dst module:
-
-verbose=0: messages are disabled
- 1: only error messages are displayed
- 2: notifications are displayed
- 3: other useful messages are displayed
- 4: debug setting
-dst_addons=0: card is a free to air (FTA) card only
- 0x20: card has a conditional access slot for scrambled channels
-
+- unscramble channels? => Documentation/dvb/ci.txt
+
+b) >= 2 cards in a box:
+- card ID order should be uprising:
+- add to etc/modules.conf or etc/modprobe.conf f. ex.: options bttv card=113 card=135
+- card ID list? => Documentation/video4linux/CARDLIST.bttv

+Uwe Bugla, April 9th, 2006
-The autodetected values are determined by the cards' "response string".
-In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
-For bug reports please send in a complete log with verbose=4 activated.
-Please also see Documentation/dvb/ci.txt.

-2b) Running multiple cards
---------------------------
-
-Examples of card ID's:
-
-Pinnacle PCTV Sat: 94
-Nebula Electronics Digi TV: 104
-pcHDTV HD-2000 TV: 112
-Twinhan DST and clones: 113
-Avermedia AverTV DVB-T 771: 123
-Avermedia AverTV DVB-T 761: 124
-DViCO FusionHDTV DVB-T Lite: 128
-DViCO FusionHDTV 5 Lite: 135
-
-Notice: The order of the card ID should be uprising:
-Example:
- $ modprobe bttv card=113 card=135
- $ modprobe dvb-bt8xx
-
-For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
-In case of further problems send questions to the mailing list: www.linuxdvb.org.
