iMac only burning partial discs - not all of the data.
Greetings all. We are using 5 mid 07 iMacs in our publishing office. When archiving work we are starting to have problems with DVD burning. Once a DVD is finished burning, we are seeing numerous instances where data that was included before the burn, is not on the final disc. Some files are not even there. No messages pop up during the burning process and everything seems to work fine until you check the final burned disc. We have experimented with various types of media, and it appears no single brand is causing it. Sometimes everything goes just fine, other times not. Has anyone run into this and has an idea on how to remedy the situation?
