dvd software to shrink iso file? (not dvd shrink)

So I have this iso file that is 7GB. I can't use DVD Shrink for some reason to shrink it (something about invalid UDF file). Is there another software that can do this? thanks
 
That "invalid UDF filesystem" error means that some of the required files and folders for DVD video (usually the AUDIO_TS) are missing. In other words, it's an invalid DVD image and you'll need to make a new image before you can shrink/burn it.
 
The reason DVD Shrink will not work for you is because an ISO file is not playable. It first has to be expanded to a playable DVD format. That is easy to do.

Once that is done, use DVD Shrink on it. It should work just fine.

Then, have DVD Shrink create a new ISO file from the shrunken playable DVD.

That's the only way I know how to do it with existing resources.
