Dvd+r burned on NEC 2500 - Error on Philips dvdr70

I try to make a backup copy of a dvd movie. I used DVDDecrypter, DVD Shrink and CopyToDVD to make a copy of the dvd on a DVD+R disk using a NEC ND2500-A drive.

I can read this disk on my PC and on a Scott DVD player. However, if I try to play it on a Philps DVDR70 I just get the message “disk contains invalid data”. I tried two different brands of DVD+Rs. If I do exactly the same thing with a DVD+RW, this disk works in the Philips player.

Any ideas?


Maybe the philips player dislikes DVD+R? But that is strange as philips is one of the main DVD+R supporters.

What media is it? Some low quality media may not work as it should in every player.

Well one was a Sony, the other a no-name cheap one. The DVD +R/W that worked was a Sony. I’ll try a DVD-R to see if that is working. Could it be something to do with the burning software? Philips support recommended Nero while I was using CopyToDVD.
