The BD-R are not for presenting good scans, but it degrades not so bad like RITEKBR2/3.
The DVD-media is much more worse than ever, MBI don´t have to put much money in R&D, they only had to produce the same they did 10 years ago.
The prices for DVD-media are low, they produce cheaper than in the past and like I said, you get here MBI everywhere (Discount-brands, maxell, Mediarange, Sony, ...)
Conclusion: They produce cheap, they sell cheap but much, so they have to make money. Or is it like with Prodisc and Gigastorage, want Philips to much moeny from them?
OK, the 1TB-discs are invented by Sony and Panasonic, but will they produce the media; if, for how long? Sony always do something at the begin, if the prices fall Sony get out.
MBI don´t have the competence to do such things like Sony, they don´t make hardware.
