MiniDV will give you full quality transfers for movie editing. MiniDV tapes are far cheaper than minidvd and they hold more data. When your footage is compressed on to a DVD there is no decompressing it. You are stuck with the final results.
There are far more advantages to using MiniDV. It sounds like that is what you need.
MiniDVD is for people who do not want to bother with editing and who have plenty of money to spend on blank media. At least with tape, you will always have the full quality original footage and you can overwrite the tape if you want to.
I am trying to understand what format would be best to use. I want to edit my movies and combine them on to one DVD disk for play back. I want to do the editing on my PC and burn the DVD using my DVD burner on my PC. My question is would it be better to use a Mini DVD camcorder or MiniDV?
