The other program uses a different reading and writing method, that work with more drives. However... it won't allow importing individual tracks or playing a CDG disc. That is the tradeoff advantage with Microstudio; you can duplicate, import individual tracks, play hard drive or CD stored tracks, and make custom assembly discs of only the songs you want.
As to Supercore CDG discs, are you using DVD media? Unless I'm wrong that is required for this format. Microstudio currently does not support DVD read/write. We have plans for that, but its' not there yet.
