don't think anyone will see this, but.... (Score 1)

i still find something puzzling about this comparison..

why a DVD+R? DVD+R holds ~4.7GBs of data while a commercially produced movie DVD holds almost double. anyone who's made a movie back-up using dvd shrink or other transcoders degrade the video quality. comparing the original DVD with the transcoded version shows a significant difference if you have a quality display.

why didn't sony use a regular commercial DVD instead of a copied version?

is it possible that they're comparing a degraded DVD back-up version to a blu-ray version? if one can tell the difference between original DVD and backed-up DVD, then of course there will be a significant difference between this backup and the blu-ray.

that's even leaving out the fanatical preaching of using taiyo yuden discs as well ;)
