How to get the Nebula, PCTV and Twinhan DST cards working
=========================================================
This class of cards has a bt878a as the PCI interface, and require the
bttv driver.
Please pay close attention to the warning about the bttv module options
below for the DST card.
1) Loading Modules
==================
In general you need to load the bttv driver, which will handle the gpio
and i2c communication for us. Next you need the common dvb-bt8xx device
driver and one frontend driver.
The bttv driver will HANG YOUR SYSTEM IF YOU DO NOT SPECIFY THE
COORECT CARD ID! A list of possible card ids can be found inside
"bttv-cards.c" inside the bttv driver package.
Pay attention to failures to load these frontends.
(E.g. dmesg, /var/log/messages).
2a) Nebula / Pinnacle PCTV
--------------------------
$ modprobe bttv i2c_hw=1 card=0x68
$ modprobe dvb-bt8xx
For Nebula cards use the "nxt6000" frontend driver:
$ modprobe nxt6000
For Pinnacle PCTV cards use the "cx24110" frontend driver:
$ modprobe cx24110
2b) TwinHan
-----------
$ modprobe bttv i2c_hw=1 card=0x71
$ modprobe dvb-bt8xx
$ modprobe dst
The value 0x71 will override the PCI type detection for dvb-bt8xx,
which is necessary for TwinHan cards.
If you're having an older card (blue color circuit) and card=0x71 locks
your machine, try using 0x68, too. If that does not work, ask on the
mailing list.
The DST module takes a couple of useful parameters, in case the dst
drivers fails to detect your type of card correctly.
dst_type takes values 0 (satellite), 1 (terrestial TV), 2 (cable).
dst_type_flags takes bit combined values:
1 = new tuner type packets. You can use this if your card is detected
and you have debug and you continually see the tuner packets not
working (make sure not a basic problem like dish alignment etc.)
2 = TS 204. If your card tunes OK, but the picture is terrible, seemingly
breaking up in one half continually, and crc fails a lot, then
this is worth a try (or trying to turn off)
4 = has symdiv. Some cards, mostly without new tuner packets, require
a symbol division algorithm. Doesn't apply to terrestial TV.
You can also specify a value to have the autodetected values turned off
(e.g. 0). The autodected values are determined bythe cards 'response
string' which you can see in your logs e.g.
dst_check_ci: recognize DST-MOT
or
dst_check_ci: unable to recognize DSTXCI or STXCI
