You can play *some* FLAC files with MC. In fact, most of your FLAC files play in MC. All except for these 180 CD collection files.
Now, you've done testing which shows that (3) different popular players (VLC, VOX, and MC) all will NOT play these files correctly. Two other players (one popular, one not) are able to play the files.
To me, this means that the files are "weird" and were probably authored in a non-standard way. Probably with some odd application, or edited in some way that's non-standard. I'm assuming you didn't rip these CDs yourself. If you did, please tell us what ripping program you used.
Maybe one of the developers will have more to say.
