VLC is an Audio/Video Player. You can download it at www.videolan.org. An other option is MPlayer. Both Players are quite fault tolerant.

Only an idea, but you could try MP3 Rage (available at www.macupdate.com). Use it to delete the ID3 tags which will maybe adjust some bits. You could also try a MP3 to Whatever (AIFF/WAV) converter (MP3 Rage can do it but I don't know if it's QuickTime based)...
