Also don't forget the FIXMORE4.POD
http://mtm2online.com/onlinehelp.shtml
"Fixmore 4 does a number of things among them it fixes the 'Hall of Mirrors' effect you see in the distance at high altitudes. It also changes water from that ugly gray to a pretty blue reminiscent of MTM1. If it appears before your 'sound.pod' file, then it will also kill the train horn noise that drives many insane".
It should be the very first pod at the top of the POD.INI text file right underneath the number at the top of the file.
Example :
fixmore4.pod
startup.pod
cockpit.pod
ui.pod
sound.pod
music.pod
etc.....etc...
