I have a RCA DRC8005, and can not figure out how to use it. Can someone please advise me how to record multiple movies onto one DVD. I record one home movie (8mm) onto a DVD+RW and once that is done I would like to record another (8mm) onto the same DVD+RW. If I do this it records over the first movie instead of recording after the first 8mm movie. Can someone please advise me - I would really appreciate it.
