Hello Folks, I am sorry if I am not posting this properly, but this is my first time and I am having troubles, I am attempting to burn a movie from my computer to a DVD, it was esy enough to get imgburn to work and when i placed the burnt dvd into my dvd player, I could see the video but there was no audio, does anyone have an idea? I would appreciate it, I hate to keep throwing out disks.
