WinAvi dvd conversion question

I used WinAvi to convert a DivX file and then opened the folder I created in DVD Shrink. Everything seemed to be going well as the video was present in the preview window but when I played the dvd in my standalone I got no picture or sound but the dvd was playing because the digital counter was moving normally.
I’m thinking it may be a Disc Region issue as I set WinAvi to convert to NTSC but by default it may be creating NTSC files related to another region code. Has anyone else had this problem and how do I solve it?

Problem solved. Turned out I was missing a .dll file
