I got a pack last week. They burn and read fine for me (LG GSA-4120 fw115 @ 4x), but I have no way to scan. I got upc 0-34707-05639-8. I don't have s/w to get a media code but I looked it up and it is suppose to be "CMC MAG AM3". Can you tell what is bad about CMC? I'm mostly concerned about how long they last.

P.S. KProbe2 says CMCMAG.AM3
