SKC Co, cant say I know much of their company or standards of recordable dvd's. Use this tool:http://dvd.identifier.cdfreaks.com/ and see if it has more detail on the media. But nevertheless it sounds like you need to try a different brand/MID.
OK after a little research, my verdict is: SKC isnt worth pissing on, While it did work well for some,(but not for others) the fact is its about a 60% hit rate, with high PIE/PIF. Media such as Taiyo Yuden, Verbatim, Maxell, and TDK, is almost flawless and has nearly a 99% hit rate, but not just that, the burn results are excellent in most drives.
