Help please - have movie which I rendered as WVI and it was not good quality (each still picture starts out choppy then focuses, plus, it can't be viewed any larger than the little Windows Media File player window.)  Re-rendered as AVI with NTSC DV wide or whatever, and the quality for full screen was much better (no choppiness) BUT, the file size is unworkable.  The WVI file size was 3MB, the AVI size is 1.99 GB....need to be able to burn this to cd.  Any advice would be greatly appreciated.  All still pictures with transitions.  Thanks.
