Embedding media into PowerPoint does not mean that the media has
become part of your PowerPoint presentation; all three media options
are really just ways to visualize the hyperlinked media file.
In order to fully save your PowerPoint and play it without any
trouble, you must have both the PowerPoint presentation and media
(audio, video or animation) files on your flash drive. When deciding
to embed media into PowerPoint, consider creating a folder into which
you save your PowerPoint presentation as well as your media files, and
copy the whole folder to your flash drive.
