ok, I do have to say, I have been shooting video for much longer than I've been editing using the PC, and over the years I have collected piles of tapes, hi8, digital hi8, mini DV. I've been learning the editing game over about the last 2 years and I haven't found one tape so far that appears to have degraded in the least, although for the most part they have only been played through once or twice in the past and the rest of the time they have been stored in vacuum bags in my closet. I have to say I went a littl crazy vacuum packing everything I could after my wife got that machine. Ok, I don't know if the vacuum packing actually does anything to preserve the tapes, but some of the tapes I have pulled to capture on my PC are over 5 years old easily, and they still look like they were filmed yesterday. Personally I have no problem or concerns archiving master tapes with the complete uncut footage. I do have some VHS that I also archived on Mini DV mainly for the smaller size as the quality is no better than the VHS was to begin with. If you are concerned that the tape will physically break down and the plastics will become brittle with age, you can always date them, and transfer the footage to a new tape at a pre-determined time. I will probably just keep all mine as is, save all that extra worry, and evaluate the condition of my archives after another 5 years.
