Multisession DVD

Is it possible to create multisession data DVDs? Prefferably with Nero software. I have read here that the overhead of multisession on a CD is about 15mb for first session and 10mb for other sessions. What is the overhead for DVD?
Thanks for any help.

I’m not 100% sure of this information, but I think you can only do multisession with DVD+R and it’s not recommended. Also, you can’t do multisession video-dvd, only data multisession. Nero can handle it. I have no way idea of the overhead…
