How do you burn more than one film to a dvd disc?

I have Nero 6 installed on my pc and it's been great for burning films i've downloaded from torrents, but one of the torrents is in 2 parts and i can't work out how to get both parts burned onto the same disc. Surely you don't need to have half a film on one disc and half on another. Does anybody know what i need to do??|||Yes... you just add BOTH parts (with ADD FILES) and when you move to the next step Nero will ask you if you want to combine them into 1 or leave them as 2... if you combine them it will just become one video file.... if you don't combine them they will both exist on the DVD, each with its own title and heading...|||try some guide on top5soft.com|||you just highlight it then click add video
