Does this happen with all MP3s, or just some? Where'd you get the MP3?

I suspect the problem is with your MCI settings. PPT uses the MCI Media
player to play MP3s and other multimedia.
I opened Sound Forge Studio and checked an MP3 which I'm able to insert
into PPT with no problems; that file also was listed as MPEG Layer 3,
which, I'll assume, is the standard MP3 encoding.
Since the codec seems to be okay, you might want to check the
information at
http://www.soniacoleman.com/Tutorials/PowerPoint/multimedia.htm -- in
section 3, there's information on what your MCI settings should look
like.
