i have found that DVDSanta is a very usefull tool into doing this, u can add multiple files, they can be differant formats and it coverts it to a Video TS / Audio TS folder, then once the conversion is done it ask to burn it, has a built in burner, and thats it!! easy and its a pretty quick encoder, i can do a 700mb avi to dvd in about 1 hour on my xpm2400 @ 2.5ghz and 512 ram .
