DB6 - forgive the repetition but the Dazzle creature will do what you are trying to do - it even comes with an editing package.
Not forgetting that you could also input the odd VHS tape (in any format) .... edit you camera shoots and the VHS stuff (all those training videos you wanted to make - or improve).... and then, if you wish, dump them out again onto standard VHS (any format).
Spoke to Dazzle about Windows XP - new CDRom with XP drivers is in the mail. It really does work quite well!!
