.wav audio compression

[huvi]

In VRS, "Recordings" tab, Under "Reduce file size using audio compression" (.wav), "Select Audio Compression Codec", I want to use "MPEG Layer-3" as compression codec.

 

My Windows 2000 based test system shows "MP Layer-3" on the list.

But not the XP based (production) system.

 

Why not?

 

I created a .wav file on the 2000 system, and tried to play it on the XP system. It worked fine.
