Well, sometimes one poster has said that if the media is labeled, that the label can warp and make the dvd unreadable. I suppose it depends on the media, if all you get in the batch (25 pk, 50pk, 100pk or more) is all good, with no defects, then storage conditions can affect it (the ideal is somewhere around 68F at 40% humidity, although so long as the humidity is fairly constant and you keep it in a dark, cool place, it should be fine). For example, my Ritek Ridata wrapper says storage conditions can vary from 23F-131F, between 10-90% humidity and things be ok, although I wouldn't want that kind of a variance. As long as it's not in the light (UV especially) and the room temperature has some variation, there may not be cause for concern there. I did read that several people said never get silver matte anything, only silver shiny or unlabeled, as that eliminates problems with labels... I haven't read anything about ritek g05 longevity being a problem necessarily, although their quality control is sometimes an issue on other threads. I guess the moral is to store it in a cool, dark place, then rescan it in a year to check it and see how that compares to the original scan. Besides that, it seems the best thing other than not trying cheap media is to get a good brand, then not worry about what you can't control.
