Problems with some Music Maestro disks

[waynec]

I have had no problem using Music Maestro disks in the past. All of a sudden I am finding problems with some of the ones I have purchased recently. Two so far. One is #6330.

When I attempt to read the files in my Plextor PX-712UF the disks start vibrating instead of spinning properly and reading the disks.

Is MM doing something with their disks now to prevent them from being accessed on computers? If not, any ideas to resolve the issue?

Thanks.
