Hi again

I am not leaving any parameter to "auto" in the full-scan dialog. I am
sorry to say but the new diff did not make any difference (21272).

I think this problem is only present on nova-s2 cards and other cards
using the same chip.

The values that i input should be correct because i have been using
the old patches before the scanner rewrite.

Example transport:
Frequency: 12015000
Polarity: Horizontal
Symbol rate: 30000000
Mod sys: DVB-S2
FEC: 3/4
Modulation: 8psk
Inversion: off
Rollof: 0.35

Mythtv output during scan:

2009-08-15 00:06:36.624 DVBChan(1:/dev/dvb/adapter1/frontend0): Old
Params: 0 auto a auto auto a a auto a v msys: UNDEFINED $
                        DVBChan(1:/dev/dvb/adapter1/frontend0): New
Params: 12015000 8psk 0 auto auto a a auto a h msys: DVB$
2009-08-15 00:06:36.624 DVBChan(1:/dev/dvb/adapter1/frontend0):
Tune(): Tuning to 1415000kHz

Cheers Staffan
