Q: 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?

Contact whoever made the DVD.

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.

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:

...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?
