I have a friend who uses an older handi-cam, palmcorder (whatever it is called) and records the video on DVD mini-disc. She would like to compile all of the mini discs into one regular DVD and send to relatives. The recorded medium on the disc is video.ts.

My question what is the better/best authoring DVD software for her to compile/edit/create a single regular size DVD for her collection of these mini DVD's?

thanks
