I know its not the DVDr's cause i bought a 50 pack and other movies have worked on them. I recently burned 2 different DVD's and for some reason, my standalone DVD player won't play them. Maybe its a region issue. The .vob files on the DVD play fine on my computer. What's going on? Is there a program that tells you the region, and/or other properties (PAL or NTSC) of .vob files?
