STEVEDAHL I purchased Disco as part of a MacUpdate promo bundle. Unfortunately, after testing it for several days I can honestly say: DISCO SUCKS!
The main problem with Disco is that it just doesn't work. I have attempted to burn 6 DVD+R DL discs with it - something I've had no trouble doing with, say, Disk Utility, Toast, etc. - and only one of them burned successfully. The rest of them failed with the completely useless message "Coaster Created." Thanks a lot, Disco!
I'd recommend just throwing your blank DVDs into the trash directly rather than waiting 40 minutes to have Disco tell you "Coaster Created."
Don't bother with this app until the developers get their act together and deliver something which actually works.
