Using Dolby™ Headphone
The Dolby Headphone utility lets you enjoy multi-channel sound sources, such as movies, with realistic
surround sound using your conventional stereo headphones.
Dolby Headphone is a signal processing system that enables your stereo headphones to realistically
portray the sound of a five-speaker playback system.
To use the Dolby Headphone feature, perform the following steps:
1.
Double click the InterVideo WinDVD icon on your desktop.
2.
On the toolbar that appears, click the Properties button (the fourth button from the left, with the
image of a wrench).
3.
On the Properties window, select the Dolby Headphone tab.
4.
To enable Dolby Headphone, check the Enable Dolby Headphone box. To change the type of
surround sound, select one of the radio buttons listed under Room Filter Setting.
5.
Click OK. The Dolby Headphone feature will now be enabled until you disable it by unchecking
Enable Dolby Headphone.
Using The Media Player On Battery Power
Since media player drives consume a lot of power, your overall battery life will be shorter when
operating the media player drive continuously (such as watching a DVD movie) than during standard
operation. Many movies run-times are longer than your LifeBook can support on a single battery. If
you are watching a DVD movie on battery power you may need to swap in an additional, charged
battery or attach AC power during the movie to view it in its entirety.
Critical Point
Media discs which do not have the Dolby Surround 5:1 symbol will not support Dolby
Headphone.
After making changes to the Dolby Headphone feature and clicking OK, wait at least ten
seconds before making another change in order to allow the system to stabilize.
CAUTION
Prolonged use of the media player drive, such as watching a DVD movie, will substantially
reduce your LifeBook’s battery life.
Many movie run-times are longer than your system can support on a single battery. If you are
watching a DVD movie on battery power you may need to swap in an additional, charged
battery or attach AC power during the movie to view it in its entirety.
Critical Point
An additional fully-charged battery is highly recommended if you will be watching DVD movies
on battery power.
