Just try. 7MHz AUTO works for me with xawtv4 cvs.bytesex.org setting
hierarchy NONE.

Hi Greg,

so many questions. It is about the au-Adelaide in dvp-apps scan/dvb-t.
And it is all in the first place about tda10046.

Something to read at first.

Please look through what Peter had already on feedback in Sept. 2006.
http://www.linuxtv.org/pipermail/linux-dvb/2006-September/thread.html

There have been also investigations/discussions about that offset issue
on the video4linux-list.
http://marc.theaimsgroup.com/?l=linux-video&r=1&b=200606&w=2

Note the DVB-T : +166 kHz Magic or Official in France ? thread.

Are you still searching Composite and S-Video on your DVICO ?
http://www.spinics.net/lists/vfl/msg30735.html

Likely a similar issue and might be easy to resolve.

Cheers,
Hermann
