I thought I would update my previous review. I continue to have excellent results with this application. Since my previous review, I did encounter one DVD that presented problems. For that DVD I finally ripped the content to a folder and burned the DVD with Popcorn; and it worked fine. Keep in mind that this was ONE DVD out of many ... so I would say that this software works almost flawlessly overall. One comment suggested that Fast DVD Copy burned a DVD with an inferior format (ISO9660), so I wrote to customer support about this. Basically, the comment is not true. This is the response I received from customer service. Again, I was very impressed with their professional response ... such a wonderful difference from the responses received from MTR (that is if you ever receive a response at all). This is the response from Velan: "Dear customer, That is not true, Fast DVD Copy burns the copies in UDF format which is the standard format for DVDs. In any case note that Fast DVD Copy uses the burning engine of the OS. Burning with Toast (or PopCorn) can sometimes produce better results, particularly when you are using an external drive that do not have a proper burning profile installed in the OS. This is because Toast includes its own burning engine that has many many years of development and supports virtually every DVD burner available in the market. Let us know if you need further help. Regards, Velan Technical Support" This is the company that deserves our support.
