']I just checked the DW1620's B7W9 firmware in MCSE and it does indeed have support for CMCMAGD01. I wouldn't think that the drive is the problem in this case. The DW1620 is an incredibly able burner, even today. :iagree:
My mistake then, I was going off of Benq's list of supported media for their 'latest' firmware for the 1620 (from their .doc file on their site). I still question the burner's support of the media rather than the media itself, even if it does have a write strategy in the firmware. There's not much info out there about CMC DL media yet, but I've not heard of this being an issue with it. It could be a bad media issue but I'm more suspicious of the burner's support. And don't give the 'CMC is crap' line, CMC typically works well in burners that support it, and HP is probably the best brand of CMC-made media you can buy.
In the future I would suggest Verbatim DL media though, as it has, by far, the best firmware support of any current DL media.
