Personally I use Toast Titanium to avoid this but you can do it directly in OS X. The process (there may be better ways but it works for me) is to make a disk image using disk utility. Set the size to be for a CD or DVD and set the format to be DOS FAT and the permissions as read/write. You then copy all of your data into the disc image and then in disk utility you select the image and click burn burn disc to create CD/DVD of the data. This should get you around your issue.
The other option is if you make it a poly object you can use the poly reduction deformer to reduce the number of polys though its liable not to look as good.

The only way I can think of to make that work is try making a poster frame of whatever you want to display. So if its a DVD cover add the image to front of the movie and set it as a poster frame for the movie. Other then that I’m not sure.
