Hi there, I've saved video and pictures from my canon camera to my computer.  I've uploaded and made a video using moviemaker.  I've then rendered the movie and created the mpeg4 file.  When I go to view or put the mpeg4 onto dvd it comes up with an error.  I've tried various software and dowloaded audio codecs.  It lets me create a wmv file which I can view but the quality is low.  Help!!!
