2003 soundclips wont play on the 2000 PPoint

[MDHS]

My 13 year old son and and his friend put together a small PPoin
presentation for school. They made the file using the 2003 version a
home on an XP machine. However upon playing it at school on an X
machine with the 2000 version of PPoint, many sound clips will not pla
. He then tried to save the file at home as a 97-2003 & 95 fil
format. This caused the file to become huge and still was unable t
play the sound files. As the school only has the 2000 edition is ther
an easy adjustment or workaround which will allow their 2003 file t
play as intended?

Thanks for your experience
