I have been trying to put movies that i have on my computer onto a dvd. For the longest time it worked, but recently whenever i try to do this it will not play on any of them, but i tried a dvd that i had burnt in the past and it works just fine. I have been trying multiple burning software's and still no luck. I have been using dvdvideosoft's Video to DVD converter, but like i said it will not play the movies now. Can anyone help me with my problem? It would be greatly appreciated.

The DVD's that i have been using are DVD+R, and the previous DVD's that work in the dvd player are also DVD+R, so i do not understand why it will not play.
