I do a lot of recording to DVD-R discs, using blank discs made by Memorex, Panasonic, etc. I have a Pioneer DVD recorder, DVR-310, which does a very good job at this and my collection has gotten pretty substantial. Today, I was reading that I can expect discs that I record myself to last from two to five years, if I observe good maintenance procedures (which I do). I thought data stored via this media (DVD) had a much longer shelf life. Should I expect all my hard work to disappear in the next few short years? If so, this is pretty discouraging. Hope I posted this to the correct forum.
