For movie lovers I have wrote previously an article on DVDSmith Movie Backup, which is able to copy the contents of a Movie DVD in your hard disk. Both unencrypted and copy-protected DVDs can be copied with that software. Today I will be writing about another software called BDlot DVD ISO Master from LotSoft which can backup DVD, but not through copying its contents but by backing it up as an ISO file. Of course it can backup copy-protected DVDs. The software can also burn any ISO file to DVD. It is also able to mount ISO files to virtual drive just like gBurner Virtual Drive or WinArchiver Virtual Drive.

While only GUI is open

While it is Backing up DVD as ISO

My Verdict
I prefer this software because it backs up as an ISO file which I can use for any purpose. It can be easily copied in USB drive (like an archive), can easily be burned on CD/DVD, can be mounted on Virtual Drive for getting same excitement as in original DVD. Viewing in Virtual drive since Virtual Drive is faster than normal CD/DVD ROM. Moreover thereby you can save your original DVD for a longer time.
I am unsure if the DVD writing speed can be adjusted and how many speeds are available, since at present I have to blank drive to test on.
There is no help file available but documentation is available online.
