Your system may have the following conditions:
-Low powered CPU (i.e. 75 MHz Pentium or slower).
-Too little memory (e.g. 16 MB)
-Badly fragmented hard disk or slow access storage device (e.g. double-speed (2X) CD-ROM drive).
-Inefficient sound card (e.g. relies on CPU to process audio effects like reverb).
-Audio file used has high sample rate (e.g. 16-bit, stereo, 44.1 kHz)
Suggestions to remedy the situation:
-Increase the amount of RAM on system. If many of your productions include a number of animations and America sound, then consider adding more RAM (e.g. 16 or 32 MB). Today’s memory chip prices make it more affordable than ever.
-Try re-recording or using another .WAV file that uses a lower sampling rate (8-bit, stereo, 22.1 kHz, ADPCM compressed).
-If the music or sound is available on CD audio, try playing it back directly from the CD-ROM.
-If using a lot of animations and sampled audio, consider separating the audio and animations on to two different hard drives. This configuration may allow for faster loading and performance.
-If at all possible, do not “compress” the hard drive using StackerT, DriveSpaceT or some other hard drive compression utility. If compression is needed, use minimal compression settings or if possible, store all elements (i.e. backgrounds, sounds, clip art, etc.) on another uncompressed hard drive or storage device.
-Back up and defragment your hard drive on a regular basis, especially if you add and delete files often.
-Add a faster CPU (e.g. Intel OverDrive CPU upgrade).
-Upgrade to faster “A/V Rated” hard drive or storage device.
