DVD ISO Compression

[hhamanishi]

My long time PC has died (running VISTA), one of the programs that I miss from my PC is DVDshrink. I also have been running my MacBook Pro for about five years and am in the process of transferring all my DVD burning capabilities to that computer. The one Mac equivalent program that I have not found for burning DVDs is an equivalent of DVDshrink that has the capability of shrinking an ISO file so that it will fit on one single layer DVD. Do you know of any Mac app that will do this?
