deanwitty, yeah you are right.
It would seem that a few years back when TDK (as I understand) was producing BD-Rs in japan they where a bit cheaper than verbatims at the time, but the most important thing is that they had great quality. Now that verbatim, TDK, and even other brands have a mix of batched made in several places. I say you can't trust them any more as you could be paying a high price for media you would count on as having high quality. It could just as well be half quality or even bad, ritek, CMC or other batches.
I could understand if they for some reason have to do this, but I see it as a big misstake that the industry behind BD-R forgot to put rules in to force all manufacturers of blu-ray media to put the mediacode on the cakebox and so on. This would have given consumers the option so buy media (regardless of brand name) that they want or can trust. Just as there are people who prefer ritek and so on.
This is having a impact on everyone, and I guess the initial problem was that blu-ray is expencive (I was and still are in the HD-DVD camp) and other problems as well with media and so on. But for just manufacturing standard blu-ray movies and so on, this is not a problem as they just make them same way as a CD, even though they hold more information etc. And today with even better technology I guess they could have produces boosted HD-DVD to larger size etc. But never mind that, it's gone and not comming back (except for CBHD). At least with DVDs half quality or good quality was OK as the technology wasn't as sensetive as blu-ray is.
So the problem for me is, what other media can you trust other than Falcon / FTI. Taiyo Yuden is good, if you have the real thing and not the fake ones. But are they pulling out of the game, who knows, they are having economic problems. And from what I can tell here, panasonic, philips and other brands, do have different batche, some could be ritek, some CMC and so on.
Would be nice with some information on this, a article with all the brands and what batched have what mediacode and so on.
