It’s not just an m2ts file - it should be a complete AVCHD folder structure - you can burn this to DVD9 and it should work in BD players.

Thanks this really helps. I thought I was just supposed to burn the video file to the disc and so I got confused when two showed ISO and the other as m2ts. I think I should be able to get it now. I will find out when my discs come in and I have the opportunity to burn a copy.
Thanks Again Harmy
