I have tried DVD-R and DVD+RW with two DVD player which suppose be able to play DVDR and DVDRW disc. But they played perfect on any PC or laptop. On the samsung player, I see a dialogue box saying "root menu" and I can open the root menu and find some video and audio folder. But can't play. On a LG, it simply say" Can't play disc" I back up the movie to HDD using shrink then write to DVDR/RW with Cyberlink software. Please help.
