the digital copy disc uses a power pc application that is no longer supported by mac os x, what can I do to obtain my digital copy?

If the OP is asking a generic question about how to run a CD-ROM, DVD or other disc that had an executable program that was a PowerPC application, he would either have to:

1. Install Snow Leopard (with Rosetta) into a partition on his hard drive or an an external hard drive, for "dual-booting" if his Mac will still boot into SL; or

2. Install Snow Leopard (with Rosetta) into Parallels to run his disc in Mt. Lion:

If the disk is that old, it's probable that the offer for the digital copy has expired; they do, something most people don't know about. If you'll tell us what movie you have, we may be able to confirm.

Regards.

...it's been documented on other sites that Disney, as well as other studios, for some unexplainable reason included PPC-only installers on their digital copy disks for some movies.

So other than running the Disney-esque DVD's digital download program in virtualized Snow Leopard, as I suggest above, what are the OP's other options, if any?

Contact whoever made the DVD.
