Do you mean DVD? I have done some testing for Jeff at Freeze frame due to my background I have a lot of DVD's available for me to test. I have tested them in Panasonic, Sony, Toshiba, Krell, and many more. Some of the cheap ones that I tried in stores came up with problems. These were the 100 dollar ones that have problems anyhow and if you are buying 100 dollar DVD players then you can not afford his DVD's Some of the old players can have trouble but we are talking about DVD players that are 4+ years old. Hope that helps ya out. I would not be concerned with it playing on your DVD player if it is working properly.
