Seems ok to me now, everuthing seem better with the patch.
I get ~55-60% signal strenght on both tuners for all channels, my LNA seems to always be 1, but I suspetct that it doesn´t work.

Hi,

Reception on primary tuner seems to be worse, more glitches in decoding (haven´t run tzap), could be foilage or lack of LNA though.
I´m not realy dependent upon LNA since my reception is ok, but I´ll verify if LNA is working without manual module load.

On the other hand the secondary tuner is now usable for all channels.

Anything I can do to help improving this patch further ?

Hi,

It did not solve the problem here. I upgraded to the latest hg version,
applied the patch, make:d and make install:ed. The signal strength
dropped from around a700 to 8000 in tzap. The second tuner is even
worse. The thing is that forcing lna activation does not seem to have
any effect (via boot parameter or modules.autoload). It worked before I
upgraded and this might explain the drop in signal strength.  If i rmmod
dvb_usb_dib0700 && modprobe dvb_usb_dib0700 force_lna_activation=1 I get
a higher signal strength. The second tuner is still worse than the first
(b800 compared to 9e00). Both tuner gets better signal strength than
before.

Best regards,
Simon
