Can you not create a new .mts file and then examine it?

hex view would probably be more helpful to look at

so aside from the first four bytes the rest looks the same in all three

some googling turned up this "MTS has 192-byte-sized packets, of which the first four bytes are a big
endian counter (some kind of time stamp, like pcr)"

looks like first packet starts 47 40 and next packet starts with 47 41 etc

also it appears that the extension is usually .m2ts after the file has been transferred off of the camera

guy here thinks he has figured out the header http://www.highdefforum.com/high-defini ... o-one.html
