DVD-RW

Had a customer ask me if it is possible to burn a portion of the DVD in RW, say 15 minutes, and then come back in a new session and add additional video to that DVD, say another 15 minutes, and so on, until the disc is filled.

Can DVDA do this? Is there any authoring software that can do this? Or do you have to start over with the original video everytime you want to add on. In other words, do a whole new burn from the beginning?

I have a Pioneer A05.

what youre referring to is multisession..

i know you can do a data dvdrw in this manner, but it runs a standard cd joliet file system, whereas if youre referring to adding clips of video over and over, the answer is no.. it cant...

theoretically it IS possible, but the file indexing (IFO) will need to be amended to include this info on the new data, but as its included within the first main data burn, the first main burn cannot be removed, (unless u replace it completely.. which is a different story)

by the looks of it, now.. but the price of DVDr now is peanuts, so u can duplicate the dvdrw to dvdr then reburn on the dvdrw if media is an issue

You cannot do this as far as I know with -R media as the laser positioning is not accurate enough. You can do this with +R/RW media.

But as has been rightly pointed out that is only a small part of the battle so as far as i know nothing makes use of the capability of the +R media even though the DVD Alliance flag it as a reason to use it over -R.

You could possibly do it with mpeg2 written as transport streams as some of the DVD cameras do but this is not playable in a DVD player so it doesn't help much.
