Please understand that FFmpeg is not an MPEG-TS editor (just 
as it is not a mov editor, this was requested or actually 
believed a few weeks ago). It is a transcoding application 
which means in your case, you cannot use transport streams 
as input and expect only certain things to change: A new 
output file will be written not necessarily with the 
properties of your input file.

That being said, please look at the following help output:
$ ffmpeg -h muxer=mpegts
