Hi all I've just purchased a Pioneer 220s (and its arrived), but I haven't yet bought any media! (Doh!) I've tried looking aroung the pioneer website to see if they have lists of recommended media but can't find any info. Was thinking of sticking with -rw as that would save burn coasters (is it the same term for dvd's?).....any recommendations or brands to stay away from? Also what are the x2 / x4 labels for? Thanks.
