I have several music video compilations on DVD and want to make my own "best of" sets. As long as there is enough space on the disc, would I be able to pick and choose individual videos and arrange them in an order of my choosing?

If so, can you recommend the programs needed? And any step-by-step instructions aside from the GREAT guide stickied at the top?

Thank you in advance.

Yes.

Any half decent authoring program. I guess preferable one that you already have.
