Glad you got things going. To use the LCD as screen 0 just change the 
screen 0 to use the CRT and screen 1 to use the DFP or TV as below. Once 
you make that change you don't need the UseDisplayDevice options if the 
LCD is always on since the CRT will always be checked first. You will 
encounter the focus problem with the mouse and keyboard if you do this.

To make mythtv FE auto-startup on the right screen you need to add 
"-display :0.1" to the command. If you're using mythdora then change the 
command in /home/mythtv/.start_frontend to:

mythfrontend -display :0.1

If using mythbuntu you need to change /etc/mythtv/session-settings to 
change MYTHFRONTEND_OPTS:

MYTHFRONTEND_OPTS="-display :0.1"

Note there was a bug in /usr/share/mythtv/mythfrontend.sh that causes it 
to fail when adding multi-word options.
