Ok, Here is my dilemma: I own a Sony DVD Home Theater System DAV-DX375. I have been burning movies with Nero 8.3.6.0 in the NTSC format. I am using Sony DVD-R discs, (120 min, 4.7 GB) The completed discs work in my KHL home theater system in the basement, but when I put them into my Sony system, it displays "CANNOT" - "PLAY". Does anyone know what I can do to fix this? Thank you in advance!!
