How to merge subtitle in MKV?

Do you have any difficulty on playing MKV movie with your blu-ray player which has no subtitle?
If yes, maybe you can refer to my solution below.

Many of the blu-ray player has USB features which supports MKV, AVI, TS playback file format.
Especially MKV movie format that supports on DTS and AC3 that has 5.1 channel surround mode.
But many of the MKV movie do not has subtitles along together.
Now you can use "mkvmerge GUI" to combine language subtitle ".srt" into the MKV file.
