Windows 7: Difficulty reading commercial data CDs

Hello,

I'm having problems viewing the first two CDs (from a set of five) that were commercially produced. The first two have files in the root directory (and some in subdirectories) that start with a dot. The last three do not.



Files that start with a dot are, by convention, HIDDEN files in linux. The first two discs are intended, I think, for Macs. Do Macs rely on such files?

I put these two discs in two different Win 7 64-bit machines and they are not recognized. But both have the exact same model SATA burner. When I put these two discs in my "pizza box" Compaq (Mandriva-only, 2.8 GHz P-4, 896 Mb RAM, EIDE burner) they are recognized straightaway.

Is it the burner or the files that start with a dot that is causing the trouble?
