Solution:
Be sure that the disk meets the standards for your country.Usually, a disk
that meets the local standards is marked with a CD logo on the label. If
you use a disc that does not meet these standards, we cannot guarantee
that it will play,or that, if it does play, the sound quality will be good.
Problem:
Playback of DVD is not smooth in Windows 2000.
Solution:
If you select the Maximum Battery mode for the Intel SpeedStep
®
technology,this problem may occur. This mode is designed to achieve
maximum battery life by switching the processor speed between the
regular low speed and half of that speed, depending on how much the
processor is used. If the use increases, Intel SpeedStep switches the
processor speed to the lower speed. Operation in this mode can severely
degrade the performance of the processor,and thus cause the playback of
a DVD to be jerky.
Toavoid or reduce this problem, you can choose any of three other modes
of operation, as follows:
