Well, squale, prepare yourself for a world of grief.
You have a couple of options. Either buy software that does this seemlessly, or use the free programs.
There are many advantages as well as disadvantages in getting the free programs:
Advantages:
1. there are many discussion groups that are sometimes very helpful.
2. if you understand how to use the program with all its bells and whistles, you can burn a very professional DVD.
3. ITS FREE!
Disadvantages:
1. it takes a lot of time to learn
2. you need a stable system for these programs to work properly.
3. no customer support, unless you search on the forms

The advantages and disadvantages of buying software:
Advantagse:
1. Its very easy to use
2. Customer support
3. usually works with all DVD players
4. able to create chapters
5. sometimes free software updates
Disadvantages:
1. they're usually costly ($30+)
2. very limited (create templates, chapters, and burn)
3. usually won't let you edit out video (i.e. commercials)
4. you'll have to be carefull on how long your show(s) are, you might have to burn 1 show on more than 1 DVD.
I currently have Arcsoft MYDVD but I don't use it any more because of its limited capabilities and because DVDs aren't cheap enough for me to play around with.
