it burned fine on another PC whch had a dual layer dvd-witer... BUT the DVD only plays on that DVD Writer now... it wont pick up on mine, is it because mine isnt Dual Layer?
On the other hand, dual-layer pressed discs (retail movies etc) should pretty much play anywhere with fewer incompatibilities. Burned discs have always been more picky.
Dual layer DVD's are expensive anyways, at least back when I bought a pack of 3 I think it was. I only used one of them. Haven't touched the other 2. If I remember correctly it was like, 20-25 bucks or so. Could of gotten 100 quality ritek dvd-r ones for that.
Again, it depends on what content you're working on that you need a dual layer or not.
