Multi Episodes to 1 DVD

I am looking for info on how I convert/burn multiple movies to 1 disc.
Basically I want to burn episodes of a TV show to disc.
I have all of the episodes in AVI format, and want to get know how I go about burning the off to disc.
I use DVDSanta to convert from AVI to VOB’s, but don’t know how I put multi episodes to 1 disc.
Assistance most welcome, as it’s driving me mad!
