Dvd Player Has Stopped Playing Burned Dvds Why Has My DVD Player Stopped Playing Original DVDs But Will Happily Play Copies?

Why has my DVD player stopped playing original DVDs but will happily play copies? - dvd player has stopped playing burned dvds

I have a Pioneer DV-370 Multi-region DVD player, a little less than 2 years is. It was fantastic, she threw herself into reading anything. However, began soon to "no disc" when an original DVD and not the game. If I can do is burn a copy of this DVD is the copy. It will continue to DVDs to play played well in the past, but not those who have not yet seen.

I confirm that I buy another DVD player I am interested in why a DVD player must be able to reproduce copies, but do not know the original CDs.
