Mine is Sony DVD player..I insert a disc and it says "CAN NOT PLAY THE DISC" and then the player shuts off. The other DVD works fine.

Possible reasons for this issue:

1. Damaged DVD discs.
2. The region code issues.
3. Video format support.

More often than not, most people play videos without noticing the media format. If the DVD video format cannot be compatible with the player program, no wonder why my DVD player won't play certain DVDs on the computer. At that point, you should install the best free DVD player for Windows and Mac OS to get rid of format support problems.

Why Won't My DVD Player Play Certain DVDs

HI,
Check the manuel some DVD Players do not support DVD RW or -R +R formats.When Ifirst put my burned movie in I got the message that the player cant play that format Just ignore that and advance the Video to where the movie is starting then all my burned movies played fine. My Pioneer BD 51 FD does support DVD RW +R -R formats so be sure that you can play burned DVD RW +R -R on your Sony player. I was in Wal Mart the other day and they had some DVD players on sale but on the box it said that they do not play DVD RW +R or -R Burned DVD's so be careful if you do buy another one I went to best buy and found mine. Check first it will save a lot of hassle later. This software works great but it may not play in your DVD Sony Player there is a list here of compatible DVD Players


OR

your disc is scratched or a pirated one
