When I bought my Canon camcorder, there were three JVC DVM60ME tapes with it. I have been looking to buy further tapes and am a bit confused when I see DV and DVM in adverts. Is there a difference? If so what? I need tapes for 'one-off' use, I will record from camera, download to computer to make discs, and then store the tapes - not using them for 'over-recording'. Any suggestions as to what tapes I should buy, and from where? Thanks, in advance for any help.
