flint, let me clarify a few things for you that i wish some one had clarified for me before i spent a bunch of money that i would have to spend again.
to fiddle with images:
don't buy a capture card. buy a digital cam and that will do the same job as the capture card, and it's a camera also. make sure digital cam has s-video in, so you can play your discs into the cam's digital tape. don't spend bucks on cam with fancy built in editing stuff, you don't need that.
get fire wire card. fire wire cam to fire wire card.
get adobe premiere (if pc) or avid. the premiere software will act like a vcr and tv set. it will let you fast forwared through the digital tape so you can exclude anything you don't want it to capture to your hard drive. you fast forward, rewind, let software know what you want, then leave and software performs what you told it to do. with capturing laser disc you would capture 10 minute segments and over lap the cut by a few frames so you can join it inside the editing software. sounds complicated but it's not. after 2 weeks of anguish, stomach aches, and screaming, you get it down.
to simply make copies of laser disc, get software that works with all in wonder card, probably $125. you can hook laser to all in wonder, and play to disc as it burns.
i hope this does not sound confusing, it's not. like all software, after you mess with it for a while you get it. there are forums for the type of software you decide on where you can get answers from other users.
