I have a 2 line VFD display on my case and MythTV always displays garbage on
the bottom line ever since I've gotten it. It'll display a nice full 2 line
clock, then display the show name on the top line with a blank bottom line.
then it's garbage on the bottom line through the rest of the screens
(episode name, etc) until we're back to the show name.

Which appears to be proper. My display is 16x2.
People on the MythTV wiki have noted this before with mythlcdserver and some
have found the fix to be to set lcdproc to 18x3 instead of 16x2.
It'd be nice to get a real solution.
