How can I decode a .MPA file to WAV?

[Chainmax]

I recently ripped an awful DVD transfer made from a family tape and am trying to improve on it. The video side is almost done, and now I'm turning my eye to the audio side. The idea is to decode the source audio, clean it and enhance it with Nero Wave Editor and then offer it and a 5.1 mix as options.
Thing is, the source is a MPA file. I assumed that meant it was MP2 since AFAIK a DVD soundtrack can only be WAV, MP2 or AC3, but, RazorLAME+LAME3.97b2fixed refuses to open the file. What can I do?

Leave it as .MPA or rename it to .MP2 and decode it with Belight or BeHappy or Winamp or GraphEdit or... etc.

I didn't think about using WinAmp. Thanks for the suggestion :) http://smilies.vidahost.com/otn/wink/thumb.gif.

P.S: trying to play the file as-is caused my system to freeze, but changing the extension to .MP2 like you said made it play perfectly. Weird.

U might have some broken file association for .MPA or a wrongly configured decoder, but if renaming to .MP2 works fine then u don´t need to sweat it very much.

U find a decode tools?

just a tip: most mp3 decoders can handle mp2 (the mp3 format is backward compatible), so renaming to mp3 might also be an option if you get stuck.

Foobar2000 can do this too.
