MythTVThemes.co.uk is a place where you can grub high quality themes for MythTV developed by Justin Hornsby. There are popular themes such ProjectGrayhem, Blootube, neon-wide and new ones. But note you cannot use those themes with MythTV built from SVN. They are suit for released versions only.
If you’re Windows MCE user you might be interested in customization of its interface. The new project - MediaCenterFX (it’s in beta stage as usual) gives you the ability to customize background images, sounds, animations, hotkeys and whole bunch more.
If you’d like to test the MediaCenterFX don’t hesitate to be a beta tester.
Personally I prefer Linux-based media software such MythTV or VDR. They are free but power and flexible.
