I am trying to author a 4.7GB file and when I choose "burn" from the menu and then choose my folder, it is giving me an error: "There is not enough disk space in the temporary folder", even though I have 450,000MB of space available. There is more than enough space. What am I doing wrong here?
Though the blank DVD media says "4.7GB", as with hard drives, that is inflated and the true usable size is about 4.37GB.
As suggested, always use AC-3 audio, and if that doesn't do it, encode the video at a lower bit rate. I've found that the Adobe formula of 560/minutes works well for me, just round the result down a bit for safety.
