The value 0x71 will override the PCI type detection for dvb-bt8xx, which
46
-
is necessary for TwinHan cards.#
47
48
-
If you're having an older card (blue color circuit) and card=0x71 locks your
49
-
machine, try using 0x68, too. If that does not work, ask on the DVB mailing list.
50
51
-
The DST module takes a couple of useful parameters, in case the
52
-
dst drivers fails to detect your type of card correctly.
53
54
-
dst_type takes values 0 (satellite), 1 (terrestial TV), 2 (cable).
55
56
-
dst_type_flags takes bit combined values:
57
-
1 = new tuner type packets. You can use this if your card is detected
58
-
and you have debug and you continually see the tuner packets not
59
-
working (make sure not a basic problem like dish alignment etc.)
60
61
-
2 = TS 204. If your card tunes OK, but the picture is terrible, seemingly
62
-
breaking up in one half continually, and crc fails a lot, then
63
-
this is worth a try (or trying to turn off)
64
65
-
4 = has symdiv. Some cards, mostly without new tuner packets, require
66
-
a symbol division algorithm. Doesn't apply to terrestial TV.
67
-
68
-
You can also specify a value to have the autodetected values turned off
69
-
(e.g. 0). The autodected values are determined bythe cards 'response
70
string' which you can see in your logs e.g.
71
72
-
dst_check_ci: recognize DST-MOT
73
74
-
or
75
-
76
-
dst_check_ci: unable to recognize DSTXCI or STXCI

The DST module takes a couple of useful parameters.
54
55
+
verbose takes values 0 to 5. These values control the verbosity level.
56
57
+
debug takes values 0 and 1. You can either disable or enable debugging.
58
59
+
dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
60
+
0x20 means it has a Conditional Access slot.
61
62
+
The autodected values are determined bythe cards 'response
63
string' which you can see in your logs e.g.

dst_get_device_id: Recognise [DSTMCI]
