Although mine DV is not the latest HD (it is PC100 from SONY, use the mini DV tape, bought in 2000'), may I provide idea on item 4 here. As the current DVD format supports up to Standard definition only. If you transfer the HD video to the DVD disk, you may not enjoy the high quality of video. From the current market, only the Blue-Ray disk media (the development of another media HD-DVD was stopped and Toshiba gave up finally) able to store the HD video. But you have to purchase another sets of Blue-Ray disk player and recorder.
