Just like rename the xxx.mov files as xxx.mp4, it will be playback well on windows media player, you can change the *.mts files to the Premiere Pro CC 2015.3 supported format such as *.wmv, *.mpg, *.mov, etc. However, when I renamed the *.mts files into *.mpg, the new issue was that it was played with some green glitches. Not sure, but it seemed that the original file was damaged a little during the renaming process.
