MacBook: battery lifespam info

following many requests, we have performed a battery lifespam test with the MacBookPro in DVD player mode.
The test has been performed with the brightness sets to 10/16 and a headphone connected to the notebook, volume being set to 50%. In this conditions, the MBPro went into sleep mode after exactly 2h30, 4 minutes after the alarm message.
So you can play most of the DVD movies on your MBPro without any problem while running on the battery.
