Ltd165

Does not support DVD+ Media

That cant be right? Even my near dead LTD 163 reads +R and +RW without problem.

DVD+R is not listed, DVD+RW is listed. But the same is true of the 163. It may be media-dependant.

Or more likely the case that +R wasn’t on the market when the spec sheet was published. +R (as you know) as a higher reflectivity than +RW so if the rewritable media works it is a pretty much nailed on banker +R will work.
