If the burner in question can change the booktype, it should also be able to change the DVD+R to DVD-ROM, it should allow the same for DVD+R DL to be recognized as DVD-ROM. BenQ for example will do it via QSuite 2.1 and LiteOn by either Kprobe2 or the Booktype 135 utility.
*IF you were asking about specs on this burner (the AD-7170A), no joy. I found plenty of pages in simplified Chinese and German, but even where Google let you translate them (only German worked), I found no specs to tell you yes or no. Liggy and Dee have some speed specs on their webpage, but there’s nothing about its bitsetting capabilities, sorry.
