[mythtv-users] mythtv-setup channel scan hang

[Craig Treleaven]

Hi:

Another thread reminded me that one of my OTA channels moved recently 
and that I should rescan.  The scan keeps hanging at the same spot, 
though.  This is 0.27-fixes* scanning an original HDHomerun.  It 
displays the message "Found 2 new non-conflicting ATSC channels".  At 
this point, the UI is non-responsive (return, up/down arrows cause no 
action) and I have to force-quit the program.

The log ends with:

Not sure if this is normal now or not.

I updated the HDHR's firmware to the latest version (20130328) but 
that didn't help.  I've restored my database backup for now.


BTW, I find the dialog boxes that pop up after the channel scan to be 
particularly obtuse.  I've been running Myth for 6 years and I've 
never known what the choices "Update all|Update manually|Ignore all" 
really mean and when I should choose one over the others.  Screen
