Hello....HELP!! We just bought the new dcr-dvd 300 sony camcorder that uses the small dvd 1.4gb. How do I burn the small one onto a full sized 4.7? If I burn it....it won't let me play it back on our computer...but it will my dvd player. BUT it also won't let me re-add more after initially burning it. We want to be able to put about 3 of our small 1.4 gb dvd's on one full sized dvd. Is there a way to add to a dvd? We do have a dvd burner, a cd burner....but either I'm an idiot or I just haven't received the correct help!!
