Lite-on 411S!Very strange

I tried two kinds of DVD: Quickso and That’s Write! But the 411S doesn’t recognize them!The green light continue to flash for ever!I tried a pair of Discs for each model but nothing!
I tried even with other different firmware but nothing!
By the way I use Princo 4x and they work fine!:wink:
