Kevin, I saw your previous post, but I can't test on something like the
310i with tda827x_config/tuner_config = 1 and I was waiting for some
confirmation. Maybe someone on the video4linux-list can test on it.

Which of the P7131 Dual cards you have. The Dual Hybrid with LNA ?

This one uses tda827x/tuner config = 2.

This configuration I can test on the recently added Asus Tiger 3in1.

We partly have heavy snowfall currently, but on the same DVB-T RF feed,
with the most critical transponder for me in upper UHF, an Asus Tiger
Revision 1 fails completely, too many errors, on a Medion Quad mplayer
starts, but picture and sound are totally distorted and unusable

On the Tiger 3in1 almost all is fine, except some rare small artifacts
from time to time. That means the LNA works for sure.

The same goes for analog TV. It is easy to recognize if the LNA is
active, since else sync issues after channel switching, a black bar
passes the screen for a while and also some slight audio issues. Others
reported sometimes flashing picture and humming noise on analog without
correctly configured LNA.

"hg head" on this machine is:

summary:     merge: http://www.linuxtv.org/hg/~hverkuil/v4l-dvb-backport

We are only 4 days apart, if LNA config = 2 should be broken at all

Few minutes later with the current v4l-dvb installed on that one.

Sorry, I seem not to be able to confirm your observation, at least the
Asus Tiger 3in1 is still fine on that critical transponder.

If I change the LNA config to 0, mplayer fails to start with only three
good and 27 bad packages. Means for me the LNA works for sure.
