Well, I do. It works really well on DVD+RW media (not DVD+R, DVD-RW or DVD-R - just DVD+RW) because the disc looks almost like a single-session disc and most applications treat it as such.
But there are exceptions, and the ISO Recorder tool was the first one that didn't work properly with my DVD+RW multi-session discs.
So why do I use DVD+RW multi-session?
I backup my documents once a week (using Nero BackItUp) to DVD+RW and when a disc is full (after 3-4 bakups) I transfer the files to permanent media (DVDÂ±R) and in order to do that I need to read all the files off the DVD+RW disc, but reading the files would take an extremely long time because there are tens of thousands of files and the slow seek speed kills reading performance, so ripping the disc as an ISO image is much faster.
I could burn my backups directly to multi-session DVDÂ±R discs, but I don't like the reduced compatibility of such multi-session discs, and I have found no tools that can rip such discs properly (with the possible exception of PlexTools on Plextor drives whcih might be able to do it.)
