Hi Def Disc Longevity

Has anybody carried out any tests as to the longevity of Bluray and HD DVD discs.
These discs obviously have far closer tolerances. As we all know, standard DVD's get quite stressed just taking them off the spindle in the boxes they come in, bending and twisting etc.
These stresses make not make any difference to a standard DVD but with the very close tolerance of Hi Def discs, these small changes to the physical disc may perhaps make these discs unplayable after a fairly short time.
I know that Hi Def discs are less forgiving if scratched especially for shorter wavelengths than red light i.e. blue and shorter still UV.
Has anyone any info. Thanks

P.S.
I have just read Doom9's comments in the forum: "failure rates were around 1 out of 3 for Blu-ray discs (I could be off with the percentages)" . Is this confirmed.
