Hi,

Werner, yes it was your device coming back in mind.

We know now about the new A/D version V1.1, saw only a fuzzy picture so
far, but looks like a KS003 something for the remote and not that PIC on
the prior, different addresses, IIRC.

That one also has the supposed LNA in the tuner area visible.

Must look it up again, but for what I remember I did not find a
difference between your Vivanco card and what Peter D. has.

We also have regspy output from a recent cardbus A/D NB, but Mauro can't
test any DVB-T currently and analog is fine on that one with card=94.

However, maybe the differences of the gpio settings in DVB-T mode
visible there may help us to figure out a pattern we miss.
