I suppose it's possible the discs aren't region 1, but they are
commercially mass produced for use in the US, so I doubt that.

I got one of them to mount at work, and it was read into a file that
can't be watched - the menu terminates on any click.  I'll have to try
mplayer track by track, although it only claims to have 1.

The other one also loaded, but it got a read error in the first 2048
sectors and quit.
