once again..it is not about how long am i going to keep the media. at least for me it is not. my LiteOn burns Memorex great enough to play in the dvd player. is all i need. i dont mean to be rude. but some of us dont mind the media that much. if i was that worried about how long it was going to keep, i would burn it like 5 times with 5 different media. sorry. once again , didnt mean to be too rude. good luck with the media who do get it.
