Can another DVD player or your computer play the disc? If yes, then the disc brand/type is most likely not compatible with your Sony. If no, then the disc is most likely faulty or not formatted correctly.

i converted it to mpg using dvdx, since i dont have a dvd burner, however it has black borders top and bottom, and its stretched horizontally, can i crop those somehow with tmpeg, or do i have to convert again using a different aspect ratio
