OK. I'll contact my technical support. There is a separate component with the system that I rarely use, designed to alter the aspects of the digital media outside of the NLE.
For instance, I am able to convert the video format from NTSC to European PAL scan-rate, then import the resulting file into the NLE for normal editing. The resulting file, when encoded, then allows for the output of a PAL video or DVD. It may be possible to adjust aspect ratio to a non-standard output.
