Thank you Mike. I started with file with extension .m2t from my FS-4HD. I want this .m2t converted to video stream. So I imported to Vegas PRo 8, edit it, and render, and try to save it as mpg file. MainConcept gives me choices of .mpg,.m2v,.m2t,and .mpa. However when I open the custom template, it says use this setting to create HDV with the extension .m2t. It goes back to square 1. That’s where I started. Is there any plug in or anyway to get mpg extension.
