How do you combine two separate DVDs?

Question

I have two one-hour lectures on two separate DVD disks ( 1.3 GB and 1.8 GB). I want to put both of them on one disk (4.7 GB space available). I have 40 GB available on HDD. The optical drive is DVD - R. I also have installed on my computer : Nero StartSmart; Power Producer 2 Gold; and of course, Windows Movie Maker.

O.K. I want to know how to combine those DVDs. Thank you so very much for your assistance.

I have encountered two problems:

1. When I copy the DVDs add try to burn them, I get "No compatable file found" (Nero).

2. I'm not given the option to choose two DVDs to burn (Power Producer)

Answer 1

you can first copy the two DVD disks to you hdd. then burn it with nero.
