New to the DVD burning thing and want to transfer all my old analog video to DVD. Bought a Sony DVDirect VRD-MC10 and am not sure which type of recordable DVD media to get or why one is better over the other. I currently use DVD+R media. What I don't understand about burning a DVD is if I don't use up all the space on the disc, why I can't burn the remaining free area later. It seems you can only attempt the burn once and I don't get why this is the case. Seems like if there is empty space on the disc, because that area is not burned, I should be available to burn it later. Not like I'm trying to burn a used segment on the disk, like with a read/write DVD.
