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 DVB mailing list.

The DST module takes a couple of useful parameters, in case the
dst drivers fails to detect your type of card correctly.
The DST module takes a couple of useful parameters.
dst_type takes values 0 (satellite), 1 (terrestial TV), 2 (cable).
verbose takes values 0 to 5. These values control the verbosity level.
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.)
debug takes values 0 and 1. You can either disable or enable debugging.
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)
dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
0x20 means it has a Conditional Access slot.
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
The autodected values are determined bythe cards 'response
string' which you can see in your logs e.g.
dst_check_ci: recognize DST-MOT
dst_get_device_id: Recognise [DSTMCI]
or
dst_check_ci: unable to recognize DSTXCI or STXCI
