[QUOTE=Bob_G;2728277]Schuster, thanks for the update, I’ve given up using my Liteon for scanning, fortunately I still have a BenQ which doesn’t seem effected by Windows 8.1[/QUOTE]
My DW-1655 (in a JMicro-bridge USB enclosure) works, most of the time. Sometimes it will think a burned DVD is “empty” and, while oddly it will run transfer rate tests up to the actual burned data content, all the disc quality stuff is disabled just like the Lite-Ons
I ran into the same capacity thing with an old NEC ND-6650A under Win 8.1; CD’s burned fine but I could not burn DVD’s using any program. They all thought the blank DVD had zero capacity and was closed (including the text below the desktop icon for the drive). The burn speed options presented made it clear that Windows was making it believe the media was a CD-R.
I’ve run filterdriverviewer on all the drives and there are NO upper or lower filters installed. Somehow Win8 has changed the way drives talk to application programs and it throws many for a fatal loop.
