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



or 

dst_get_device_id: Recognise [DSTMCI]



dst_check_ci: unable to recognize DSTXCI or STXCI
