Speed vs. quality

When I use the free dowload version of dvdfab, I use easy cd creator to burn the movie. It allows me to set the copy speed (I usually use 2x).
I have tried using the trial version -platinum-but, because I don’t need easy cd creator,the program sets the copy speed. Am I losing any quality that way ? What is the copy speed using Platinum ?

The ‘slower is better’ idea for DVD Burn speeds is largely a myth. DVDs generally burn best at or near their rated speeds, as optimized by the drive’s firmware and the media itself. For example, 8x media generally burns best at 4-8x, 16x media generally burns best at 8-12x.
