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.
