Plaing Mp3 sound in Adobe Acrobat 9 PRO

Ok, so the PDF references sound files that are on a different drive from the PDF? Not a good idea because it's not cross platform, so Acrobat can't trust the drive to exists. The media should either be embedded, on the same drive, or at a remote URI.

Thanks Thomp, I guess I shouls also mention that both the thesis and the sound files are on the same flash drives. But I am ignorant about what this means "embedded, on the same drive" (is that like everything in the same directory?) and I have never posted anything to a remote URL. What is the easiest way to do that?

Thanks So much for your help I was about ready for the State Hospital!

Legacy media files (created in Acrobat 9 and earlier) require external software to play, and this leads to some significant security issues. As such, users must individually grant "trust" to each media file or folder before the content will play. If that content is on a removable drive Acrobat/Reader knows that even if the filename is the same as before, it could be a different copy - so it doesn't permanently-store the trust rule. Once the content is stored in a permanent location it should be possible to remember the decision, but everyone will be asked at least once.

The use of legacy media is strongly discouraged, not least because of the need to track all these permissions, but also because it remains a security problem. Whenever possible users with access to Acrobat 9 or later should use the native Rich Media annotations instead. These won't display a warning, no matter where the PDF is stored.
