ConvertXtoDVD from VSO software works great, I've used it many times for converting AVI, MPG, WMV, and etc to DVD files and creating a simple menu. It is a small program, unlike the bulky Nero. It is $49, but there is a free trial. I then use ImgBurn (free) to burn to DVD. Have used both on XP and Vista. These 2 programs have pretty much replaced Nero for me, along with Alcohol 120%.
