Thanks Terry:
I finally got some time to try this again and I am not having any luck.
Whatever format I select to render the video in it stops around 23 percent, the video is a mix of still pictures and video all on the same track with a music track. It all plays great in the preview. I think there must be a problem in the area where it stops rendering, I am not smart enough to see it. Today I transfered it over to a faster computer with more memory to see if it would help and it stopped in the same place. Also I do not see where to chose AC3 audio.
Sorry to be so much bother.
Thanks again for your help
Chuck
