when i was backing up my movie dvds which were dvd9,i used dvdshrink and also i used clonedvd,why have these apps got a feature like dvd9 to dvd5 or compression and why hasn't dvdfab platinum got this feature?

I can back up dvds splitting 2 dvd5 by using dvdfab but i want to compres %20 or %30 with dvdfab

producers should think this thread

and in addition dvdfab and vso software (copy2DVD) are working great together
