All players, like Windows Media Player or mplayer expect a MMS stream to be in form:
mms://server:1755
VLC expects additional "h" at the end:
mmsh://server:1755
As a result, no other player besides VLC can play such stream: "mmsh://server:1755". VLC won't play this link: mms://server:1755.
Why does VLC need "h" at the end of "mms" streams?
Because of this, it's impossible to put a piece of HTML code on a website and expect it to work with Windows (which uses Windows Media Player), and Linux (which can use VLC plugin in Mozilla/Firefox):
