It will, in fact, be utterly central to the problem. The program will be
trying to do special tricks to check if the CD is authentic, ie not a
burnt copy. The copy you have will be "cracked" - the game binary will
have been modified to skip this check.

That authenticity check will almost certainly use nasty low-level hacks,
direct hardware access, or other ickyness. Most of them do.
Unsurprisingly, it doesn't work in Classic - thus your copy running when
legit copies do not.

I pointed out that this was probably the problem quite some time ago. 

This is one of the many reasons copy protection only hurts legitimate
users - abusers get around it trivially.

Crack the game if you can find a crack, and your legally purchased copy
will cease preventing you from running it because it thinks you've
stolen it.
