"As is I have a firewire capture port (which I use for my DV tapes), but nothing for composite."
Yeah, you don't want to use your camcorder as a capture device for the LDs. It will work, but you get much better quality from a real capture board (although using firewire to download your digital tapes is fine, because there's no conversion going on.)
