Can this unit record AUDIO ONLY using either a +DVD, R or RW or a CD-R? Is there a CD+R? IF yes does the VIDEO cable need to be connected even though VIDEO will NOT be present? I plan to transfer my open reel tapes to disc. I can use a vcr but I have an abundance of DVD+Rs I can use as this will be a RAW transfer, no editing. One disc equals on reel. I prefer to use RWs for video as I do with VHS tapes for the same reason,re- recordability.
