Adding chapters to DVD title

[Fyrsten]

Hi guys and girls

(I didnt know where to ask this question, so I used the newbies section. Feel free to move it into a more suitable section if necessary.)

I have recorded a concert for a friend of mine using a mini-DV video camera. A local choir performing classic christmas songs like "Silent Night" and "Come all ye faithfull" (copyright restrictions and royalities are sorted, in case you wonder, because Im making this for that choir, which is gonna give it to friends and family for christmas. My friend is the leader of the choir, and Im doing this for free to make him happy.)

I've transferred the recording into my computer using Firewire and using some crap bundled software who were shipped along with my DVD burner. Pinnacle something.

Now I have VOB, IFO and BUP files, and its playable in PowerDVD. But the problem is that there are no chapters. There should be a chapter for each song so the poor viewers don't have to watch the entire feature every time, but being able to skip to their favorite songs.
But I dont know how to make them, or if there is any software out there capable of editing the VOB files and insert chapters where I want them.

I also wonder if the chapters are stored in the IFO, BUP or in the VOB files themselves, and if it's possible to add chapters using a IFO editor of some sort.

As it's christmas in just three weeks, I hope to have the master DVD disc ready this week. It's to be given to a DVD printing company for duplication, as the choir wants 200 copies of it.

If you need to know more, feel free to ask.

I hope that someone can help me solve this problem.

Thanks in advance.
