I wish the component players had better read failure programming to overcome those scratches. I have tried finding reviews for the better players with no luck. Using a laptop sometimes handles scratches better.
In my experience, DVD players have gotten steadily more able to deal with damaged discs over the years. But still, if one doesn't play in one player, it might play in another, or maybe a blueray machine will play it. It's not predictable.
Sometimes, washing the disc will get it to play. Sometimes, rubbing a tiny bit of oil (!) on it will get it to play.
