@TechConnectify technically you're wrong: #DVD players and drives also need to have a second #IR #Laser to read #CDs...

They are just in the same assembly...

In fact, I have a slimline #BDXL burner which has at least 4 lasers since #BDXL have an even shorter wavelenght than #BD & #HDDVD.

So OFC it'll assume it's a #CD first, as #DVDs were propably just an afterthought of an existing product it succeeded at the high end.
