Xubuntu 14.04 live DVD does not boot

 When installing 14.04 LTS on an HP laptop PC Pavillion dv6, it boots from the DVD, shows the screen with the keyboard symbol at the bottom and then the screen goes blank. DVD activity continues for a bit and then the activity stops and the laptop is unresponsive.

Note, the same DVD was used to successfully install 14.04 on two different Dell dsktop PC's
