I think the only way to tell with NVE is to see how long things take (Hours = transcoding).
My suggestion for the easiest way is to get a free one-month trial of Ulead's DVD Movie Factory, which will allow the importation of VIDEO_TS folders from a hard drive, and add successive ones of these to a compilation. It is very easy to make a menu and the software contains a burning facility to get the finished DVD to disc.
There's a freeware route using ImgBurn, DVD Decrypter, DVD Styler and then ImgBurn again to write to disc, but it isn't as straightforward as the free trial of DVD Movie Factory. It all depends on how curious you are, or whether the job just needs to be done.
