Universal using diffrent kind of discs?

[love4blu]

So, I just bought my first two Universal blus (Mummy and Mummy Returns).

As I looked on the back side of the disc, I couldn't find the BVDL, BVSS codes... Instead, there were only the usual bunch of numbers....

I suppose that as new manufacturers get into play, we'll see different kind of discs. I just hope this will keep quality up and bring prices down.
