I've been testing some CDR's (of sermons in audio CD format) bought from my church with Nero CD Speed. The discs turn out to be mostly Lead Data, some CMC, a little Gigastorage and some Ritek. All were unlabled before they were burned. The recorder is unknown but the duplicater has several bays & records at either 4x or 8x. I'm not sure which speed it uses. They tell me it takes 20 minutes to copy a CD if it's not already in the duplicators hard drive. All CDR's play fine in the home CD player plus the car & home computer. Everything tests fine except the Ritek discs which show lots of c2 errors on every one I tried. Yet those Ritek discs play ok... The Digital Research Riteks I used for data showed no errors for 32x burns. A TDK Ritek I have tested fine too and so did some Maxell Riteks I tested. . Maybe the church got a bad batch of discs? This is what they are made of.
