The purpose of the auto-builds is to allow you to still use package
management in your Ubuntu based system but also be able to avail
yourself of the latest fixes for mythtv. If you want the latest fixes
without needing to learn how to compile the code - this is your best
bet.

Install this .deb package as root :
