Dvd burning help

i have several movies on my pc that are in avi format. i am trying to burn them and nothing seems to be working. I am using nero 7 can anyone help me figure out how to do this. i have tried everything. Please

You will need to convert the .avi file to DVD format, you can use a free software such as DVD Flick

Are you burning as data or converting and burning for use in a standalone DVD player?

I’d guess converting, in which case try a different tool. ConvertXtoDVD is one of the better choices (not free), DVD Flick and FAVC are also decent (free).
