Sony DRX-810UL won't recognize blank dvd

I have a DRX-810UL with Dynex DVD+R 16x. The pc only accepts it as a blank cd. I’ve gone in and deselected the cd burning mode, but it won’t open the blank dvd. This combination of dvds and burner has worked before, but I guess not using them for a couple of months makes them mad (I offered taking them to therapy, but they would go)
Any ideas?

Hi and Welcome!

have you tried using a CD/DVD writing application like Nero, Roxio etc.? Windows built-in CD writing function supports only CD media.


I had roxio, and it wasn’t working either, but I installed Nero and it’s working now. Thanks Michael
