Update: New version available!
Two more screens got some love today. The key bindings setup now looks good and the screen size settings, too. Get the new theme version 1.6 here. Special thanks to Chris, who made me aware that the compression I was using was not lzma but lzma2. To uncompress use "tar xfvJ 2010.11.20-Willi.tar.lzma2" within your themes directory ("/usr/share/mythtv/themes" in Ubuntu and derivatives).
