I want to take my 1.4 gig mini 80 mm dvd-rw's that I use for my Sony DVD 300 camcorder and put them onto a bigger 4.7 gig dvd disc so that I can have a backup. Then I can erase the mini dvd-rws so that I can reuse them again. When I try to burn the mini dvd-rw's to a 4.7 gig dvd disc it creates a folder named DVD_RTAV on the 4.7 Gig Disc. Inside that folder there are 3 files. One is VR_MANG that is a BUP File. I also have a file in the folder called VR_MANGR.IFO and one more that is VR_MOVIE.VRO I can't get the 4.7 gig dvd disc to play in any of my dvd players including my computer. What did I do wrong? This is my first time trying to do this so I am looking for some suggestions.
