DVD Duplication Information

Someone told me that when we are burning a cd/dvd, we should close all other programs(like mp3, video players). If there are some programs running in the background, the cd/dvd created by burning will be of low quality and some data loss may occur during burning. Is this true?

Yes,but to some extent.

I need a free download of dvd burning software that isn’t going to leave a watermark on the picture after I burn it. IT HAS TO BE COMPATIBLE WITH A MAC. I have Leopard.

You can try this dvd burner for mac.
