So heres the story, we filmed all day at mt snow with my buddies HD mini DV cam. Forget exact model but it was JVC. But he had to take his cam cam home so I copped the tape. I got home and put it in my reg mini dv cam, sony, and it wont show up on the viewfinder screen or download. Same EXACT tapes I use in my reg dv cam. Is it cause it was filmed in HD and mine is not or is it just a freak thing.
