Here is a data page for this LG burner and it is Panasonic Chipped and also there are no firmware updates for it yet.

I would try Verbatim CD-R's in it they are a better brand of CD-R and just might work. Also some burners actually do not burn CD-R's at all and from what I have read the reports on this LG are not too good
