>>>>What burning program do you use?
I use DVDfab and ImgBurn.
>>>>What burn speed?
I used to burn at 4X for many years without any problem but now I tried all speeds.
>>>>If they are freezing in a stand alone player
Yes they are freezing in a standalone player 'QONIX DVD-3900'. But if I play other dvds that are burned on a different computer they don't freeze.
