Yup, free is always good if you can find it. <g>
Here is what I suspect is happening. The MCI player is very picky about
what qualifies as an mpeg or mpeg-2. (It pretty much follows the Redbook
standard.) The unfortunate thing is there are tons of creation tools that
allow people to create these files in a manner that does not meet the
requirements. They allow users to output non-standard sizes, frames per
second, resolution, color depth, codecs, etc.
As I see it you have a couple of options, obtain the original media file and
use a professional tool (usually costs a few dollars) to encode it in a
manner that meets the Redbook standard, or as you have suggested use the
Windows Media Player in the presentation.
As an FYI, you can use my add in freely for two weeks and discard it if you
don't think it's worth the $50. I do not limit the functionality in anyway
during the trial period so help yourself.
