Thanks, Case. Why did you removed from your site?. Is not good or not necesary?. Thanks.

Is there any differents among the three mppdec.exe???

One uses the replaygain data in the MPC file in "album" mode, one in "title" mode, and one ignores it and decodes normally. Try http://www.replaygain.org/ for more info about Replay Gain.
