from a mail by me back in November 2005 when the tda8275a tuner started
working with the tda10046a demodulator/channel decoder.

This did work for me that time.

"scan" from dvb-apps-1.1.1 until the recent mercurial dvb-apps produces
valid channels, even with the wrong FEC in the initial tuning file.
(in dvb-apps-1.1.1 de-Frankfurt is not there yet, too old)

./scan dvb-t/de-Frankfurt-orig

Guess I missed that change, since I had most set to AUTO in my
channels.conf files and "scan" produced valid channels even with the now
wrong FEC in the initial tuning file on the previously also changed 7MHz
VHF transponder ...

All your fixes are fine.

Thanks,
Hermann
