I have a LITE-ON DVDRW SOHW-1633S BS0C (ATA) burner. The firmware is "BS0C" and this is the firmware that came installed from the factory. I recently bought some Verbatim DataLife Plus DVD-R's in a 5 pack at Circuit City. They have a media code of MCC 02RG20. These discs worked great and I understand they are among the best in quality. I ran out of discs so I bought a 25 spindle of them at Best Buy. I bought the box that had the "AZO" sticker on it because I remember the other box had the AZO sticker on it. The new discs have a media code of MCC 03RG20. I took these home and tried to burn a DVD and I have ended up with 2/2 coasters. DVD Decrypter fails writing after the LeadIn track. The message is "Cannot Write Medium - Incompatible format". What the hell is going on? The only difference is the 1 digit in the media code and the fact that the new discs can burn up to 16x (but I was burning at 1x anyways!).
