Great software and great service.
I downloaded and tried out DumboFab DVD Ripper and found it fantastic, fast and very easy to use. Then I went to rip a Blu-ray and realised of course I should've bought Blu-ray Ripper (that also rips DVDs) I sent DumboFab Sales an email and they sent me back a very simple way to upgrade me to Blu-ray Ripper just for the difference in original cost. I thought this was extremely good service and I'm very happy with the software. It's the easiest I've found for archiving my collection of DVDs and Blu-rays. Highly recommended by me.
