Comment Successfully Change to .OGG in Windows (Score 2, Informative) 687
I was able to change the .wma test file to .ogg using CDex. I had to download a DLL for it to be able to read the WMA file, but I just google'd for it and it came up lickety split. So basically:
1) Install CDex
2) Download WalMart WMA Song
3) Attempt to convert file, download whatever DLL it tells you too, then try again.
4) Congratulations, you have a OGG/MP3/whatever format you want.
