You know, you could be right. I merely made an assumption.
The stamper code of these CMC-made "powered by TY" discs contains both a TY-style code AND a CMC-style code, which is why I assumed the equipment made a trip; if it was all equipment that CMC had before, then I assumed the codes would still be in the normal CMC format. Reference a post made by Two Degrees...
(found here, in a thread I see you've visited before :http://club.myce.com/f33/cmc-pro-powered-ty-341120/#post2782431)
GH008127 is a TY-format stamper code.
CMDR470-TYMSM01-127 0320 is a CMC-format stamper code (a little tweaked from the usual).
The hub code is a normal CMC hub code.
When CMC made/make TDK and Verbatim media (among others), they at the least have to use the 'correct' dye, and the stamper code remained similar to that from TDK and Verbatim, making me guess that they also had to use the correct stampers for said discs.
The rest of the equipment, however, could have just been what CMC already had, meaning there wasn't necessarily a move of 100% of the equipment (backed up by the fact that the hub codes are still CMC-style hub codes).
That's where my thinking came from. I, too, would love to hear more info on this whole process went down -- whether any equipment was moved, or if they just had to tweak a few parameters to match what is expected of the YUDEN000... and TYG... media codes.
