Thinking about the way I might use a HDD-DVDR, I would record to HD, edit/delete as I please, and then transfer any edited material I really want to keep on to DVD-R (with the benefit of near universal playback compatibility). The Panasonics record DVD-RAM (and DVD-R) - my question is, how would DVD-RAM be of benefit in my usage scenario? Or in anybody's? Just hoping to make the right decision in the next few weeks! TIA.
