erasing Writable DVDs

Archived from groups: rec.video.desktop (More info?)

Has anyone had an experience where when burning over a DVD that has another
video on it does not work correctly? I managed to copy over a another video
on a DVD and it did not look as sharp as if I used a brand new disc. I have
a + RW DVD burner in my computer and I use that type of Disc.

that is precisely what transpired, but on a copy that played flawlessly, I
did detect a lower clarity than a burn from a new disc. I was using Nero
for the first time and really like it compared to Mydvd and dvdit

I bet the orignal DVD is a dual layer disc, and in the process of
converting it to work on one single layer disc, losses have to occur.

Green AND blue with the new dual-layer DVD media, surely?
