PPS losing audio sync

[Phil Troupe]

Three presentations all of similar length - 30
minutes .wav audio, 24 slides (half with custom
animations), timing set up via 'rehearse timing' for main
slides, custom animation timings set via numeric entry.
When saved as a .pps and burned to CD, one syncs perfectly
every time on any machine, the other two drift farther off
through the length of the program (up to :09 seconds by
the end). I've tried 11,025hz, 22,050hz mono and stereo
audio tracks, doesn't seem to matter. HELP! Thank you.

It's amazing that one works consistently. PowerPoint doesn't "do timing"
very well, or at all. Running from CD will nearly always slow things down
because CD drives are much slower than hard disks. I can't tell you why one
works, but I can tell you that what's happening with the other two is normal
and to be expected. The only advice I offer people is if a presentation is
to be distributed to multiple machines, design it so there is no dependency
on synchronized timing.
