Comment (by mmorin):

 Indeed, with just

 {{{
 ffmpeg -ss 0 -to 5 -i 00122.MTS start_00122.MTS
 }}}

 the output of both files is now around 5 seconds. No, I haven't realized
 the implications of `-c copy` and I have read
 [https://ffmpeg.org/ffmpeg.html#Stream-copy the manual section]. Why does
 it have a different effect on one input sample and not the other?
