It would depend what format there in at the moment. An excellent FREE program for converting AVI (divx/xdiv) to DVD is called, VSO Divx to DVD .. http://www.vso-software.fr/ In my opinion that is the best, extremely easy to use. Just one click.
Apart from that Nero and Ulead DVD MovieFactory.

I assume you have a DV camcorder. Typically they connect to the computer using either a firewire or USB connection.
I have both Pinnacle Studio and Sony Movie Studio - they are both good programs. Honestly, for simplicity, Pinnacle Studio is probably easiest to use. It is more than just DVD burning software (they both are). They allow you to capture the video to your computer, set up DVD movies, render the movies to DVD format, and then burn to DVD.
