I've been renting tons of movies from netflix lately, especially very recent movies that have just been released, and I find that some of them are still being released on single-layer DVD. Why is that? You would think that by now, studio would want to release their DVDs with both layers to maximize bitrate. It makes no sense, to me anyway. The biggest amount of single-layer DVDs I found was from Columbia, and in their case, I'm sure that they're only doing it, to release a superbit later, but what about other studios? In my opinion every single DVD being released today, should in fact be 2 layers with the maximum bitrate regardless of the title. Especially, when the DVDs in question have no other special features, the least they can do, is release them with good audio/video quality!
