Hope you don't mind, I merged your 2 posts into one thread.
Mitsubishi (AKA MCC) is better known as Verbatim, however not all Verbatim are MCC.
Your 52327S can eat most anything you feed it, but if you want high speed and quality in the same CDR, go with Ritek TG, Mitsubishi or TY. Search the CDR tests for those names and you will see the brands that are using them.
In the USA, Maxell 48x is always Ritek, Maxell CDR-Pro (made in Japan) is always TY, and Verbatim DataLifePlus 48x has so far always been MCC.
