Greetings. I will accept most brands of discs with the exception of MAXELL, MEMOREX or cheap generics discs. If you use discs from the above brands, please let me know and we'll talk about it. I generally use Klone, Sony, TDK certified plus (non-Ritek), and Mitsui. I took my sound grades off of this list, let me know which show(s) you are interested in and I'll give you the full lowdown.
