I just purchased DVD +R DVDs to put photos on, that I want to be able to play on a Panasonic DVD Player. The literature indicates that it will play DVD +R that has been finalized. I tried using the Windows DVD Maker and adjusted the speed to medium. and I also tried using the media center. The DVDs are not recognized on the Player. I did select the finish button while burning but what else am i supposed to do to close the dvd? the dvd burner is a blu ray and while it is capable of lightscribe i bought single layer dvds.
