Ok... which file from windows explorer?

If I double click on the dvd drive, it loads windvd, which isn't what I want at all.

Opening the dvd using explorer offers me Audio_TS or Video_TS - do I want one of those? If I choose something from the video folder, will I still get the audio?

The video folder looks like the attached file. Do I want one of those? Which one?

The actual dvd output is a collection of individual 5 minute programmes (which handbrake recognised as individual chapters). Can I choose them? If so, how?
