dst drivers fails to detect your type of card correctly.
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: debug takes values 0 and 1. You can either disable or enable debugging.
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 dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
breaking up in one half continually, and crc fails a lot, then 0x20 means it has a Conditional Access slot.
this is worth a try (or trying to turn off)
