ok i know its been over and over and over again here im sure, but whats the real difference with the +/- media? i read some where the -r is more comp. in dvd players and +r is less comp. but i didnt see any other Real difference. ive been using +r and have had no problems and they seem to be the same price. my burner supports either format(ive burnd one -R and had no problems with it) but is there any quality issues? will one one of them die out over time faster? any thing different??
