There is a question I see popping on and on at forums but with no "good" answer. I've copied a DVD to my hard drive and it is about 6.6 GB. Is there any software that will help me to burn it into a 4.3 GB disk?

  • Do you know anybody that's managed to do that? If you copied the DVD on the hard drive and it's 6.6 GB, I'm not sure you can fit it on a single layer DVD. – alex Sep 2 '09 at 8:13
  • @alex: the size can be reduced by removing special features and extra audio tracks (e.g. DTS, foreign languages, commentary), or if necessary, re-encoding it at a lower quality. – mark4o Sep 7 '09 at 1:29

Toast has worked well for me...


I personally use Burn and LiquidCD. Both free.

To rip DVDs you can use MacTheRipper or DVD2One.


DVD Remaster has worked well for me in the past download. It also comes bundled with an application called Fairmount which will decrypt DVDs and mount them as a drive for making local copies, transcoding, or burning back to DVD.


Use Burn to burn your files on Mac OS X. It can also convert videos to formats, that a DVD-player can read.

Oh, and it's free... :)

  • I've used burn but I think it can not scale-down from 6.6 to 4.3GB I do not know if there is any way to do this... – Dimitrios Mistriotis Aug 20 '09 at 13:26
  • Toast compresses the files, but you need to pay for it. – alimack Feb 18 '10 at 16:11

I do all my burning needs with Disco. If you looking for more features, then Toast is a good alternative. It is rather expensive though.


If you mount the image file with Disk Utility, you should have a Burn option to do that.

Otherwise use this command:

hdiutil burn image.iso

Burn image to optical media in an attached burning device.

Run man hdiutil to see the documentation page, or hdiutil burn -help for list of parameters.

To list all burning devices, run: hdiutil burn -list.

  • This question is 9 years old and states, “I've copied a DVD to my hard drive and it is about 6.6 GB. Is there any software that will help me to burn it into a 4.3 GB disk?” So the issue is the original poster wants to magically cram the contents of a dual layer DVD onto a single layer DVD. The basic use of the hdiutil burn functionality will not solve this unsolvable problem. – JakeGould Feb 3 '18 at 22:40
