Please take your time to read the replies you get. Read them on a computer and not a smart phone. It seems that there is a disconnect between Q and A. As you may know, we are users and not tech support so it is possible that we become frustrated and become surly or just won't respond.
Forget about format. It is a minor element. The best is uncompressed (large file size) AVI or more compressed like mp4 (smaller file size). You were given the answer long ago. Whatever the format that you get from your camcorder is the right format. Who knows what is going to be available 100 years from now.
What camcorder? Perhaps that will help us help you. Yes, that is important especially about finalizing the discs. What PROGRAM are you using to capture the videos from the discs.
Properly stored and best quality DVD should last for the for the foreseeable future (Read this). There are special ones that last longer but who knows. Use only the best quality blank DVD for storage. Store brands and Memorex are not the best quality. Have you thought about using thumb drives for long term storage?
