I just picked up a samsung hd931 (the one with the 720p/1080i upconversion) but I cannot get any of my dvd+r's to work on it. I've tried generics, memorex, and philips, and none of them work. All 3 of these types of dvd+r's work on my old piece of shit panasonic player. I burn at 2.4X and 4X using dvd decrypter. The manual says something about "dvd+r playback depends on recording process", but I can't find anything specific as to what this means. Anyone have any luck with dvd+r's with this thing? thanks
