紅色的是播放器
藍色係俾Quicktime播wmv格式影片的runtime
淺藍色的是影片的格式,以.mpg為副檔名的影片是以mpeg格式錄製

there are not really much relationship between them...
here's what i know, and hope making use of this chance to let ppl correct me if i am wrong:

Quicktime Player: developed by apple, built-in video player for mac os
support limited video codec only, you can download Perian Plug-in to make it play more formats of video

Windows Media Player: a built-in player for windows

VLC / Mplayer: Freeware. Able to play DVD, TS folder, streaming, and almost any popular video formats
Windows version VLC need no installing and therefore make it a good choice other than media player classic

Flip4Mac: something that need $ so I don't know. check here: http://www.flip4mac.com/

AVI: M$ product. video format which is claim to be the best quality, yet also make the video super big in size, because it didn't compress and can play in almost any player.
but nowadays AVI is enhanced by DIVX and many variation that make things complicated....

wmv: developed by M$ again, basically can only be played by Windows media player. but VLC/Mplayer seems to be support it. never know as I never got a wmv at hand. M$ said it give similiar quality to AVI but much smaller in size...

mp3: full name mpeg-1 audio layer 3. An file format that store audio signal in a lossy way. the most common type of music file. But those who really love music and in need of quality won't use it, they will use tta, flac, ape, or even....wav....

mp4: a very common video format now....but its a very vague and unclear definition to call it just "mp4", because there are too much compression methods...
copy from wiki:

Video compression       
ISO/IEC
MJPEG · Motion JPEG 2000 · MPEG-1 · MPEG-2 · MPEG-4 ASP · MPEG-4/AVC

ITU-T
H.120 · H.261 · H.262 · H.263 · H.264

Others
AMV · AVS · Bink · Dirac · Indeo · Pixlet · RealVideo · RTVideo  · SheerVideo  · Smacker · Snow  · Theora · VC-1 · VP6 · VP7 · WMV

Audio compression       
ISO/IEC

ITU-T
G.711 · G.719 · G.722 · G.722.1 · G.722.2 · G.723 · G.723.1 · G.726 · G.728 · G.729 · G.729.1 · G.729a

Others
AC3 · AMR · Apple Lossless · ATRAC · FLAC · iLBC · Monkey's Audio · μ-law · Musepack · Nellymoser · OptimFROG · RealAudio · RTAudio · SHN · Siren · Speex · Vorbis · WavPack · WMA · TAK

--------------
basically, unless you asked a more specific question, otherwise you should go Wiki and type all those format name and see by yourself....
