I have used a few different options.

1 The easiest is probabley DVDAuthor by Pegasys systems. This is totally intuitive.
2 Next is Nero Vision Express 6.6.
3 DVDMaestro is an old piece of software, but I like it. It is clunky.
4 Then there is Adobe Encore which is more powerful than the majority of users needs.
5 DVDRecode is useful formodifying existing VIDEO_TS structures.

I would recommend DVD Author as an excellent place to start. It is probably all you would ever need. My skype is brummymax, and i do suggest you skype me.
