I usually burn my content on DVDs using Nero Burn Lite 10 using data burning feature. But when I explore any movie DVD, it shows VIDEO_TS, AUDIO_TS, IFO, BUP, VTS and all such things.
What are those things? What is the use of them and how to create such format DVDs? Can we write more than once on a DVD? I mean if any space is still left?
