Join the club. Although I still have my PCM Hi-MD masters, I have been on the phone to a Sony service centre & I have been told that there is no way of converting .OMA files to standard wave formats using SonicStage. SonicStage can convert from CD/wave to MD, but not the other way, he said. Which is what I found aswell. At least in the version I have. Whoever designed this software is not strong with the force. Anyway, according to Mr. Sony Serviceman, if the DRM tag info is removed from the .OMA files, then conversion to wave is easy. He mentioned a $20 or thereabouts software that does this. Bloody stupid, it is. Paying for additional software so we can extract our own recordings from the MD. My 1GB discs are filled with PCM audio recordings from stage microphones used in a theatre production I filmed. My next purchase will NOT be another minidisc. There are better digital audio recorders that do not mess you around with this nonsense. Had I known this when I bought the unit, I would not have bought it. Bloody salesmen. Worse than Darth Vader, they are.
