KMplayer

If you're looking for a something to play almost any file you throw at it, KMPlayer is the choice. Period. I'm rather impressed on how well it plays various media relatively no lag. With a pleasing skinnable interface, it handles many forms of media, Divx, MKV, OGM, AVI, etc. And when I say it can handle MKV it can. Where VLC and rulesPlayer are simply able to run MKV format video... KMPlayer dominates it. I'd give a rather humoring simile on The App's performance but I'm supposed to be informative(Thanks Katja). Anyway, there is a nifty option in the configuration menu that allows you to save setting to the application folder. That or you could just make a file named 'KMPCfg.ini' with the following lines added to it:

[\Software\KMPlayer\KMP2.0\OptionArea]
ConfigUseIni=int:1

I must add that this app is smaller than rulesPlayer, for those of you that use it on your USB drives and are always looking for a more efficient use of space. You can grab a copy of KMPlayer here.

Screamer

For those of you who hate bring their entire media library with them and hate constantly changing out music on their USB device. Fear not, with Screamer you can listen to music over the web. But how is this different from Media players like Winamp? Screamer has built-in presets that are updated frequently if not daily. Another feature I like is being able to record streams on the fly. Best of all, Screamer is portable.

Updates for Pidgin

When I wrote a batch for making Pidgin into a portable install for your USB drive/device, I didn't write in any lines for Aspell. Well its about time I did wouldn't you agree?

The original:
::First things first. I'm in UR Echo, dumping my excludes.
Echo \perlmod\ >Exclude1
Echo \locale\ >Exclude2
Echo pidgin-uninst.exe >Exclude3
mkdir Programs
::base dirs
MKDIR Programs\Pidgin\
MKDIR Programs\GTK\
::Pidgin Lines
MKDIR Programs\Pidgin\sounds\
MKDIR Programs\Pidgin\pixmaps\
:: Went with XCOPY instead :p
XCOPY "C:\Program Files\Pidgin\*.*" "Programs\Pidgin\" /E /H /G /EXCLUDE:Exclude1+Exclude2+Exclude3
DEL Programs\Pidgin\plugins\perl.dll
DEL Programs\Pidgin\plugins\tcl.dll
REN Programs\Pidgin\Pidgin.exe Pidgin-portable.exe
:: /Pidgin lines

:: GTK lines "C:\Program Files\Common Files\GTK\2.0"
MKDIR Programs\GTK\
MKDIR Programs\GTK\bin\
MKDIR Programs\GTK\etc\
MKDIR Programs\GTK\lib\
MKDIR Programs\GTK\share\
XCOPY "C:\Program Files\Common Files\GTK\2.0\bin\*.*" "Programs\GTK\bin\" /E /H /G
XCOPY "C:\Program Files\Common Files\GTK\2.0\etc\*.*" "Programs\GTK\etc\" /E /H /G
XCOPY "C:\Program Files\Common Files\GTK\2.0\lib\*.*" "Programs\GTK\lib\" /E /H /G /EXCLUDE:Exclude2
XCOPY "C:\Program Files\Common Files\GTK\2.0\share\*.*" "Programs\GTK\share\" /E /H /G
::/GTK lines
Del Exclude1
Del Exclude2
Del Exclude3

Plus Aspell:

::Aspell lines
mkdir \Programs\Aspell\bin
xcopy "C:\Program Files\Aspell\bin\Aspell-15.dll" "Programs\Aspell\bin\" /E /H /G
xcopy "C:\Program Files\Aspell\data\*.*" "Programs\Aspell\data\" /E /H /G
xcopy "C:\Program Files\Aspell\dict\*.*" "Programs\Aspell\dict\" /E /H /G
::/Aspell lines

And if you want to import your current existing profile(optional):

Xcopy "%appdata%\.purple\*.*" "\programs\.purple\"

Now you have a complete install that is ready for your USB drive, just that simple.
