Just recently, my dvd player/burner (Lite-On DVD RW LDW-411S) does not play my DVD +R's. It will play a factory DVD (example: Dodgeball Unrated Special Edition) but will not play anything (television or movie I've burnded onto my DVD R+. The burning programs I use are ImgBurn and ConvertXtoDVD VSO Software. I don't know what I did to make this problem come about and I've no idea which direction to take to solve this. I'm not familiar with proper firmware or codecs. I use Windows XP operating system, my computer is a Gateway. Any help given is appreciated.
