Problem setting sounds in WindowsXP

I having a problem with getting WindowsXP to play a certain wav file.

When I goto "sounds and audio devices" and bring up the "properties"

box then goto "sounds" I try to get "start Windows" to play a wav

file

with the opening theme from "Star Trek Next Generation" It loads and

plays when I test it with the "play" button, but when I shut down

windows and re-open it, the wav only plays for like 4 notes then

stops...Windows goes on to load up without any problems. When I set

"start Windows" with another wav file, like the them from the

"orignal

Star Trek" it works fine...plays all the way. I have played the

"STNG"

wav file on my Windows media player, and on my iTunes player...no

problems playing the whole file...I have even played the "STNG" wav

file on a program called "Wave Pad" and again it plays without a

problem and doesn't show any visable drops or spaces. Any help on

this? Thank you, John
