I am working with AVCHD clips in V9 (64 bit). If I choose to selectively prerender and select *.m2t file format with a BluRay template, the render process occurs but the timeline does not show the horizontal bar that indicates a section of the timeline has been prerenderd and play back in the preview window is slow and unchanged from the non rendered sections. If I choose a template other than a BluRay template then everythings works correctly. Is this normal. What is the purpose of BluRay templates if they do not work?
