Leon Nero will do it and it's just a matter of selecting the files you want as a batch in the 'File Select' dialogue and it will tell u if you have over-shot the size limit for the blank dvd and you can remove / add / files etc before burning.
Otherwise have a look at FreeStudio 5 here:

I use it and it works well. Just do what's obvious for any of the modules u use from the program. Straight forward.
Good Luck
