I am brand new at this whole DVD back up thing. I have DVD Studio Pro 2 and am planning on buying the new Plextor 16x DVD reader writer. The main reason I am considering it is A) I heard Plextor makes the best DVD drives AND B) It’s a dual layer burner. I am a quality junkie, I like to have the best, without paying the most. Also I have found that the dual layer discs are around $10 a piece. My question is this, how much quality am I losing by compressing my DVD movies to a single layer disc, as opposed to no compression on a dual layer disc. So is there anyone out there that has a good perspective between the two that could give me some advice?
