If I buy an actual recorder and record to dvd-r discs, can any editing be done if I use someone's computer's drive? I know absolutely nothing about burning dvds via computer. I am just wondering if there is any way to do an A-B deletion and make chapter marks. My guess is that you can delete whatever you want, but not change the marks. I am only talking about -r discs, not -rw. I know there would be no way to use that space again also, but I don't see why A-B editing could not be done. The recorder I am considering lets you cut out chapters after recording, but you have to lose the whole chapter, not just the part you want to delete! Like I said, I know nothing about this. Oh and also, can you take a disc out of the recorder without finalizing and then put it back in later to finalize? Or it must be finalized to even eject it?
