Can i use hard or symbolic links on a DVD which needs to be Mac and Windows readable?

I'm producing a DVD and want to try to save some space to fit it onto a single-layer disk rather than dual-layer. There are a lot of repeated files on there and it occurred to me that I could have a "canonical" example of each of them in a special folder and then just link all of the others to that, and thus save space.

Is this actually possible? I know how to make symbolic links on Mac (where the disk is bued), but I don't know if they're going to work when they're read back off disk, or whether it will actually just copy the file onto the disk when buing anyway, or something else.

Obviously I could find some of this out by experiment, wasting a lot of blank disks in the process, but thought i'd ask here first.

Any advice welcome! Max
