VGM Stream help ps3

My issue is I would like to get all the sounds and music off of my ps3 game called M.A.G.

I did the directions, both for winamp and foobar2000. Well, hopefully right

In foobar2000, I would play for example, credits_01.xvag

a small screen would pop up and say this:
Unable to open item for playback (Unsupported format or corrupted file):
"D:\PS3_GAME\USRDIR\run\mag\ps3\audio\streams\music \credits_01.xvag"

but it was added to the playlist, it recongnized .xvag

I have the external .dlls in the main foobar2000 folder

If anyone knows what to do or can help me out I would gladly appreciate it! it has been bugging me for months!
