>Will the ATI TV Wonder work with an AMD Athlon Processor
It should, but I have not tried it and currently do not have the TV board available to try.
>do I need to remove the existing output only video card in my Presario 7000
No. If do you are not going to see anything on your monitor
>do you have to have a tv hooked up too
No. The TV card essentially turns you computer into a TV set, among other things. TV programs appear in a Windows Window and other Windows doing other things can be doing other things at the same time (suggest reading the review referenced in my last post for details).
>will it work with just the VCR?
(Obviously from the last answer) yes
>I plan on doing the editing through Windows Moviemaker...is this good software?
Dunno; someone else will have to answer that one. Larry
