It depend's on the quality you're willing to accept, the quality of the avi, whether they're 1/2 or 1 hour episode's. You should be able to burn 4 1 hour episode's and maintain good quality. DVD Flick is free and should do, here's an old guide to look over: http://beginwithsoftware.com/videoguides/dvd-flick-guide.htmlConvertXtoDVD is payware but easy to use, the trial will put a watermark in your video, simple menu though, DVD Flick give's a choice, I think. Another option is a player capable of playing avi, you could burn as data but nobody without one could play them except on a computer. Both burn, DVD Flick with ImgBurn, ConvertXtoDVD has it's own burner or you can use ImgBurn (free).
