Consumer burnable optical discs be it CD or DVD fails for they are manufactured to be chemically simulating the laser dynamics of true press-mastered discs, thus very very poor backup choices for long term (3+ months) so if the same thing is still stick with Blu-Ray expect me to be adopting them only when what here today gone in the way of 8-track and vinyl. If you don't believe me, then you haven't seen a disc being stored in open room; those must be stored in air-tight (uh exaggerated) closed cupboard.
I hope one of those special DVD making process does take form from academics to some true use. One of them is already beating Blu-Ray amount to a pulp. It would be ideal if the same super DVD disc, if put to a standard player it goes standard def, but into an HD player goes HD.
