Hi,

I guess the first thing is to make sure you transfer it to the other
computer and not play it from CD or thumb drive. Also, what is your hardware
acceleration set at? Turning it on can make a real difference if you have a
good computer and video card. This link talks about turning it off or
setting it back:

How to set graphics hardware acceleration back

But first, try using it in your slideshow setup options. For example, in
2003: Slideshow| Set up show| performance area, use hardware graphics
acceleration check box. Let us know how you get on.

In addition to what Glen has suggested, If your music selection was from a commercial CD, it is still there. All music files with the exception of WAV files are linked to your presentation and not inserted.

 I created a 380 slide PPT with music inported from a CD, regarding a business
 trip to China.  I compressed all slides and then saved on a CD and Jump
 Drive.  When I tried to play either one on another computer, the slide
 transistion was jerky and the music was lost.  The drivers on both computers
 are upgraded and I have tried everthing within my level of expertise that the
 self-help tools suggests.  Any experts out there willing to talk me through
 this?
