The opinions are mixed as to whether it's a good idea to use a camera as a feeder but my opinion is that if it's a cheap solution, does not degrade the image quality and you don't mind the wear and tear on the cam, go for it. It will not harm the tape. I know plenty of people that have gone this route with fine results and still are able to use the camera as a backup. The manufacturers and some dealers will tell you not to use a cam because they want to sell $1500++ decks, not $300.00 mini DV cams.
