Copying DVD to a blank using 1 DVD drive

Hi Guys,

General advice needed here...

I have been given a recently made DVD of family cine films to put onto another DVD but I only have the one drive in my pc!! I have movie maker on my system which I've never used before now.
But would it work if I was to make a copy of the DVD on my hard drive and then burn back on to a new DVD?

Also should I go for rewritable DVD's or not?

what dvd recording software are you using any one worth its salt should have a copy dvd function ?

I haven't got any software what would you recommend for a first time?

I use nero but its expensive

if u want to try a cheap one then try gburner 30 day trial avaiable which will do the job
