DVD Not Playing

I have been using WinAvi Converter v7.6 to make my DVD’s from AVI files. Over the past few days though after burning the DVD’s are not playing either on my stand alone DVD player or on my PC. When i put the burnt DVD into my pc it comes up saying that there is nothing on the DVD at all. I haven’t done anything different than what i usually do and all my other DVD’s that I have made from AVI files have turned out fine and play on both my PC and DVD player. Does anyone have any suggestions? Any help would be great!!! (Sorry this was originally posted in the wrong place but couldn’t figure out how to get it moved.)
