[mythtvnz] Help! Can't change channels in LiveTV

[Simon Green]

Hi guys,

Have just installed a new MythTV box, but have a problem. I can't
change channels in LiveTV. If I schedule a recording, it will change
channel and record fine, but won't change channels when using LiveTV.

When I start LiveTV it will show the last channel I recorded. The up
and down buttons will change the OSD, but the channel itself does not
change. Nothing in the mythfrontend, backend logs or syslog reveal any
problems (i've attached the output below).

Have deleted and re-added the card in mythtv-setup, but that doesn't
fix it. Running Ubuntu Fesity AMD64 with a PVR-150 card, and the
packages that came in Ubuntu.

Any ideas?
