I have noticed the exact problem you are describing, so I am glad you
are looking into it.

I would suggest creating a ticket for the issue and attaching your
patch to the ticket.

Also, you may want to pop into the myth IRC development channel, and
discuss the issue there.  Stuart Morgan is the king of MythUI stuff
(IRC nic stuartm), and he probably the best person to ask about this
stuff.  The IRC channel is on irc.freenode.net and the channel name is
mythtv
