I have burning discs for quite a while on dvd-r using DVD decrypter or also dvd fab and shrinking with dvd shrink and then recording with cd burner xp pro 3. They all play fine on my living room dvd player. Which is a Philips dvp642/37. I have recently purchased a Philips dvp3150v/37 which I read only plays +r so I burnt a movie to a +r using the same format and I get a playback function may not be available for this disc error. Also my parents recently purchased a vcr dvd burner combo which is supposed to play -r and +r, but that too gets the same error as my new Philips. Will neither of these players play .vob files? Is there a way to burn that will be compatible with all 3 players?
