I am fairly new to the world of DVD burning. I’ve done a bit of research today on DL discs and see that they have about double the space of a SL disc. I keep reading “can hold a longer movie” but I’m not so concerned with length as I am with quality. If I have a 2-hour video to burn, does it go without saying that because the DL disc has more space, the quality of the video will be better (I read somewhere that compression isn’t necessary with DLs?) Or am I missing something obvious?
