I can't record but one vhs movie on the -R dvd. Some of the tapes only has 30 mon or less but when I try to get another tape to record it says the dvd is full. The DVD has not been finalized and it is recording in the long record time. What do I need to do in order to record two different tapes on one -R DVD? Help Please email me at nanof_two@hotmail.com Thanks
