Manufactured Cds -- difference in brand names?

I remember reading somewhere that there are differences in the quality of manufactured cds. For example, a BMG music club disc would not be as good as the original from Sony or Epic. True?

Also, I buy most of my cds used on Amazon. Never had a bad one. Any downside to used cds?
CDP error correction is now good enough for people to buy used CDs with little risk. Those of us with "vintage" players are in another boat, ime.
False.This has been in discussion before. From my rememberance, the CD's from BMG, Columbia House, etc are no different than the ones in the store.
7671 is correct. BMG discs are made on the same lines at the same time as the "brand name" discs...only the labels are different.
