Copying VHS to DVD Using Canopus 300

When I use my Canopus 300 to Convert my (bought) VHS tapes to Digital, using my Mac. The contents of the movie fade from normal color to Vary Dark. Is this copy protection? If so, how do I address this? I just want to update my purchased VHS Analog tapes to updated Digital media. Help!
