What are compression artifacts? Are there names for different types of artifacts arising from compression?
I backed up the Labyrinth with 1Click with a compression of like 37% if I remember correctly. When I watch the movie I see a very brief white flash at the bottom of the screen only when the camera switches from face to face or cuts from angle to angle. While it is not a perfect copy this movie is still most certainly watchable.
My other question is regarding Dual-Layer DVD media. No compression should be needed here right? This should make it a perfect copy with no artifacts, right??
