[mythtvnz] tuning problems

[mythtvnz@lists.linuxnut.co.nz]

Well I've got my PVR-150 working nicely... the new outside yagi is
pointing roughly in the right direction and is providing a better picture
than the old rabbits ears.

However mythtv-backend is not displaying the right channels.  I have an
epg source set up and working fine, but the only channel that shows in
mythfrontend is TV1, which is numbered "1000" and is labelled as "Fiji
News"

scantv finds no channels - it complains that "Television" is an invalid
input.  Nowhere can I see how to tell it to look for "Tuner 0"

ptune.pl complains:
mythtv:~# /usr/src/ivtv-0.4.0/utils/perl/ptune.pl

ptune-iu.pl does the same.

Where am I going wrong?  this feels so close to working right!
