What model of camcorder is your video coming from and what format and resolution is it?
What are your project settings, as listed under the Edit menu?
Have you ensured that you have the latest version of Quicktime, per the program's requirements?
Is there a particular Publish & Share option that's giving you this error or do they all? Try Publish & Share/Computer/AVI as a test.
What's a "basic Sony"? Sony makes everything from point and shoot still cameras to professional video camcorders selling for thousands of dollars.
Along with Steve G's comments and suggestions, this Adobe KB Article: http://helpx.adobe.com/premiere-pro/kb/error-compiling-movie-rendering-or.html
might be helpful with the "Compiling Movie" error. Though it lists Premiere Pro versions, there is some overlaps in PrE.
Hope that is helpful.
