I have been successfully exporting back to both my Sony HDV camcorders for several weeks now but NOT 100% OF THE TIME. I think that the settings have to be EXACTLY as they are in the TRANSPORT STREAM TEMPLATE. For example, when I have modified the Quality from 70% to a higher setting, or checked the "add keyframe at clip edge" then the export would mostly fail. Also, if I have "perform smart render" ticked then it can cause the file to get an MPG extension name instead of the required M2T. If this happens you must highlight the".mpg" and replace it with the ".m2t" extension.
Hope this helps those who are still frustrated..
