It appears Encore's automatic encoding of an avi (for standalone playback)cannot "read" the size of a data file in order to properly compress it so both fit on the disc.
For example: If I put a 2-hr project on the disc along with an avi file - say 500 Mb (as a data file -- not compressed)Encore seems to try and encode the project to fill the disc -- leaving insufficient room for the data file.
I presume there must be some way to "reserve size" for the data file -- or do I have to manually guess/set the encoding for the project to leave enought space for the data file?
How did you add your ROM content? You have to move all the files you want to add to a single folder, then point Encore to that folder from the Disc tab/panel.
If you add the ROM content first, then Encore's automatic transcoding will take the size of the ROM content into account when it calculates what bit rate should be used to transcode the DVD-Video parts of the program.
