I have a Plextor dvd burner (16X) and a Sony 5-disc dvd player. Both are supposed to be compatible with either dvd +/-r. However, last night I was playing a burned dvd in my dvd player and it started skipping around and looking pixelated. I had been burning at 8X with dvd shrink. Someone told me the dvd +r are better, I had been using the dvd -r . Anyone have any advice? I went to radio shack (b/c it is near my office) and bought some philips dvd +r and when I get home I am going to try them out. Anyone know if those are decent? Also, what is the deal with "booktype set to DVD-ROM"; I've read some posts that make mention to that and how that is why dvd +r are better. Sorry for such a long (confused) post! matt.
