My dvd-s52 notifies me that DVD-HD disk is unplayable

Unfortunately, this is not Netflix.

Contact Netflix with your issue. They have an online service to report those issues.

You may have to reset the player to original factory condition, know your Netflix account username and password, or reset your password if you only know your username.

Clean the laser lens

if you deside to sell your dvd unit (not the screens) let me know.

for sound may be you are using above 96khz frequency which your reciever is unable to adjust and always try to play original dvds in players if you want your player's life long.

Harry, two possibilities that are immediately apparent. One, the lens on the drive is dirty. Stop by a department store and buy a CD/DVD laser lens cleaner CD and put it in the drive several times, making sure that it tries to read it each time. This can brush away the debris on the lens and it may work again. Two, the drive motor or lens assembly (that moves) has failed. My experience is that these drives have a 2-3 year life span. Luckily, they are now bargain-priced and you can pick them up at your local discount store and replace them yourself.

If everything works fine except that disk then its the disk its self.
either there is a scratch on the disk or it was a bad burn from the manufacturer.
