When you talk capture (glossary link in http://forums.adobe.com/message/2276578 at the top) you are talking Firewire... only
Newer, non-tape cameras work via USB and a copy of media from a memory chip or built-in hard drive or even a mini-dvd writer
To go from VHS to computer you need to digitise and use a Firewire port
There are other devices that will connect to a VHS player and then a computer USB port, but they generally do not create DV AVI for "easiest" editing
