I am using this program that I found on my computer to burn files to dvd. I tried using a dvd r (I have 9.25 GB worth of files), but it said that I had to insert a cd r or cd rw. So I inserted a cd rw and tried putting one of the video files (400 MB worth) on the cd rw. It took it, burned it, and ejected it. Then I tried putting it on my dvd player on my laptop and on my tv and it didn't work. Then I tried it on my media player and the video worked. The picture was a little grainy though. Why wouldn't my dvd r work? I can't use a cd rw for all of my files because they won't fit.
