Hmm... nope ;p

"-c copy" do NOT convert at all, so you always get source codec on 
output (when container support that codec, of course).

AND

.mpg container does NOT support MPEG-2 video (only MPEG-1), that's why 
in the previous example ffmpeg converted mpeg2video to mpeg1video

AND

the "default" container that supports mpeg2video is .m2ts (then .ts)
