I have two laptops with similar specs, both running XP. I have a large file
(20Mb) full of wipe animations and transitions, and containing two MPEG2
movies.

Both machines play the movies fine, but on one of the laptops the animations
judder. On the other they are smoothe.

Any ideas?

Be sure that PPT is using hardware acceleration (SLIDE
SHOW >> SET UP SHOW >> PERFORMANCE section at bottom). Use
this setting to improve animations, UNLESS the computer
has a video chip that uses shared memory (ie. intel
xtreme).

Martin,

Sorry....I've gotta ask.....have you defragged it lately?

Updated the graphics card drivers?

Using DMA on the hard drives (or has one reverted back to PIO mode) ?

Cheers

Hi Troy

Curiosity insists that I ask: why unless the video chip uses shared memory?

TAJ,

Thanks. I've already asked the client to defrag and update the drivers. But
what's DMA and PIO and how do I do whatever one does to them? I'm only a PPT
man myself...

DMA is to do with how quick your computer can get the data from the hard drives.

Direct Memory Architecture (or something like that).

If a particular computer has repeated read errors from a particular drive (even a cd-rom drive)....it will revert back
from DMA (fast) mode to PI0 (read slow) mode.

This just about explains it in terms I can understand...

The reason I know about it...was because a particular PC started to get the slows....sound stuttering and the like. I
found that the PC has reverted back to PIO mode. Switching it back to DMA made it ohhh so much faster.

Cheers

Thanks - now I can frighten my clients to death!
