I am frustrated by the large files of the video that a DVD limited to only one video. I wanted to burn two videos (two chapters). I tried compressing the video to make it smaller, but when I add the video to the app the size went back to too big for two videos for a DVD. Is there anything wrong with my procedures? I have 22 videos (each of them about an hour). One video is about 3 gb. Your advice would be helpful. Thank you.
