I recently burned a project to DVD. It's a data disc, and seems to have worked fine, about 1.2 GB of the four available on the DVD-R I burned with a Superdrive on my G4 desktop. I told it to write session in Toast 7 Titanium, but when i try to burn something else to the disc, Toast rejects it. With DVD's, can you only burn one data disc? No multiple sessions? It's okay if this is the case, I just want to know. Thanks so much for any replies.
