The pop3 of my mail provider is in delay. (copy/paste)

Mike, kick me, for not thinking twice. Of course this was it all about!
And as long there is no tuner address detection on DVB-T, we need the
new config. Started with this Twinhan saa713x, followed by the CTX953
and also this new Avermedia hybrid now. Hard these days to ack new
hardware without having it, but yes, this one needs a new config
currently in saa7134-dvb.

Think we saw the new variant without DVB-T support already on the
video4linux-list. Analog video was working with the Avermedia Go 007
entry, no analog audio support, radio likely needs to be changed to amux
TV, but with these new DVB-T variants, how to get analog initialization
seems not to be clear yet.

Should be added to DVB-T just now, but the existence of the LNA should
also be tested with config=0, if this makes any difference. On a good
photo, the LNA should also become visible, since this one has no
shielding ... The remote looks like on the other Aver/initial_Medion
stuff, but can't identify the usual controller on the fuzzy pictures.

If we have on the v4l-wiki and in comments, what is not yet supported,
we better move them in. To wait until _everything_ is perfect seems no
solution either. On the saa7133/35/31e only dual language support is
missing, Soeren gets hangs after 5 days, still could be a bug ...

The driver is not clever enough for cardbus power handling and advanced
suspend modes, but else really not bad. Any help is welcome!

If we get trouble, we can at least share it.

Cheers,
Hermann
