Hi folks..I have a question about the Ritek 2x -R disks..(A03 I believe they are called). I have the DRU-500AX burner and I normally buy cheap disks and dont normally have any problems with them..But I was unhappy with my last batch so I found a 50 Pack of Ritek's on ebay for $54 including shipping so I bought them. I havent recieved them yet but I was wondering if there is anything negative about these disks I should be aware of. I read on here that most people love the Ritek's..Is there any compatability issues with the Sony burner that I should be aware of or are these like the top of the line disks? Thanks in advance!
