I have an old Alcohol 120% CD/DVD image file that I'd like to convert to an .iso image. I have tried simply renaming the file thus (disregarding the 4 KB .mds file):

video.mdf --> video.iso.

This sort of worked. Most of the video played perfectly (in VLC) but then the final three minutes were silent with a blank screen.

How should I go about doing this?

  • Did you consider reinstalling Alcohol (on a PC or virtual machine) and converting the image into .iso? – nohillside Oct 23 '11 at 14:01
  • Yes, but the image is so old that I don't want to go to the trouble of installing Windows just to access it. I can do this on the command line on my Xubuntu box but I wonder if there's a way on the Mac. Thanks anyway. – boehj Oct 23 '11 at 14:26
  • How do you do it under Linux then? – nohillside Oct 23 '11 at 14:32
  • Using the mdf2iso tool @Eir mentions. :) It's late here now but I'll give this a go in the morning. – boehj Oct 23 '11 at 16:37

You can use very simple command line program mdf2iso for this. it is available via MacPorts (for example).

PS: This utility can be also used in any Linux, *BSD and Windows systems

  • Thanks for this. I'll try in the morning and report back. I may try and find the source and compile it altho' I'll probably only ever use it the one time. Cheers. – boehj Oct 23 '11 at 16:39
  • How is your experience with it? – Eir Nym Nov 16 '11 at 17:25

    Really sorry, I totally forgot about this. Worked a treat. Many thanks. – boehj Nov 17 '11 at 4:29

Handbrake is able to read quite a lot of video formats. It shares a bunch of libraries with VLC anyway so you may be able to convert your files as well.

Another way, if you only need to mount the image, is to use DAMON Tools for Mac. Not free but if the trial expires it can be uninstalled/reinstalled using AppCleaner.
