Are there any other programs like DVD Shrink that work just as good or maybe even quicker?
I have DVD Shrink 3.2 but it won't allow me to open ISO files. Any suggestions would be greatly appreciated.
Have you already tried "File - Open Disc Image..."? If yes, what kind of error do you encounter?A probable workaround is to mount the ISO file on a virtual disc drive (like Daemon Tools).
Nero Recode/Nero Vision have a functionality that is very similar to DVD Shrink.
I open ISO files with DVDShrink by clicking Control I.
There are many other dvd transcoders that are fairly quick, but most are not free. ReJig is free, but I much prefer Shrink.
If it's purely speed you're after then DVD2One is the fastest transcoder available, but it's not free.
Also, as has been suggested, if you mount the ISO with Daemon Tools or DVDFab Virtual Drive (which is free) the files can then be processed with any software you like.
