Hello
the way i did it was using a standalone capturing device such as advc300 from canopus, lots of people agree this device is perfect for this situation, but i must warn you, it's expensive...
you need to have some knowledge on capturing analog video using your pc, then you could use a software like vegas pro to edit and make the best out your analog videos, that requires some more knowledge and extra dollars...
other option would be using a standalone dvd recorder but it will lower the source video quality a lot...
what i can tell you for a fact is that you do not, most certainly want to use your camera/camcorder/projector to capture/digitize your analog videos, that is just wrong, plain and simple, considering modern technology.
you could also send the analog material to a video lab and they will do the job for you, but again, that requires some extra dollars...
if you decide to do this yourself, i'd suggest you visit
VideoHelp.com - Forum, Guides, Tools and hardware lists lots of tutorials,free tools, guides....
almost forgot, you could also use a mini Dv camcorder as "pass through" device, assuming the pc has a fire wire connection, and an "input" plug on the camcorder, picture it like this: vhs... plugs to camcorder...firewire to pc...start capturing on windows. bit tricky but i did it, might not work with all Dv cams...
hope this helps
cheers
