I have a sony model VPCJ111FX. MY CD/DVD RW combo plays cd's but when it comes to playing dvd's some will play others will not. It is set to US regaion 1. It's a Optiarc dvd RW model AD-7700H. I checked for updates none found I just got a dvd for a breathing machine for my asthma and the dvd will not play. But I can put in my sons cartoon dvd it plays just fine.
Any help is in advance
