I am seeing this problem when changing from an SD channel to an HD channel and created a ticket for this (#9177). There is a
work around for this (see the ticket).
I am also seeing this same error message when attempting to switch to my analog tuner (that has never worked with myth TV) I
attempted to open another ticket for this problem (#9178), but because it generates the same error message, it was immediately
closed. So now I am patiently waiting for the first bug to get fixed so I can reopen #9178, and get back to work on attempting
to get my analog tuner to work. (I have been trying to get the analog tuner to work for more than a year).
