It says 4x on the disc, so I set ImgBurn at 4x. Then it told me the disc only had about 25gb and it wanted to burn about 48gb. So I recopied it at 23.145gb and was able to burn, it read "burned successfully". So I tried playing the DVD in my bluray player, and it began skipping at around four in a half minutes into the movie. The counter on the DVD player stopped, then a couple minutes later the scenes in the movie started repeating themselves.
Then I decided to go back to using the VSO engine and at only 2x the speed to see if that would make a difference. Same result, it managed to burn the DVD but it's unplayable, it just repeats the scenes all the time.
And I am using Optimum DVD's which I bought at Fry's, don't know if those are good quality or not. I can try a different routine to copy and burn, but I want to get it right. Because every time I try to copy and it fails, then I waste a DVD, and those blank blu-rays get expensive :Z
