I exported to avi (from avi original) using premiere 6.5, then used tmpgenc to make them mpeg-2's, the used tmpgenc dvd author pro to author and finally nero to burn. when I watch the video using my dvd player on the tv, I sometimes get mini boxes that show up on screen, sometimes in one area, sometimes in another. does this sound like a burning problem or is the dvd disc itself not good? disc is LG. any suggs to how to check this? thanks!
