SMTHPlayer
smthplayer is a cross-platform player for the smooth streaming format
... Windows version that includes a full mplayer pack (mencoder is included, even if it's not necessary to smthplayer), Faad 2.7 and bgrun.exe (needed in Windows to run background processes), because it's more difficult for Windows users to find precompiled binaries. I've not checked the binaries (I've just found them on the Internet), so use them AT YOUR OWN RISK.
The program has been SUCCESSFULLY tested on Ubuntu 10.04 - 11.04 - 12.04, Windows XP and Windows 7.
