I need a god player that can read these formats:
-avi
-rmbv
-rm
-flv
-mkv
-wmw
-mp4
-ogm
-ogg

Tried VLC?

I'd say VLC or MPC. Personally, I like MPC.

The good side of VLC is that it's got his own codec pack, but sometimes it fails to play a certain types of files, personally I use CCCP codec pack with Media Player Classic and additional Alternative codecs to play quicktime and realtime files and it works perfect.

i use vlc,but something go wrong and i cant use it anymore
i tried deinstaling but failed....

and i use mpc too

I use Windows Media Player and downloaded the Combined Community Codec Pack. It lets me play everything. You can download the pack here: http://www.cccp-project.net/.

I use Real player, I think it comes with the code pack

VLC player is small so if u dont wanna dl much - yeah. media player is good only if u get all the codecs runnin

Media Player Classic...
If its filesize of 4mb is too big for you, then compress it using PECompact.
I shrunk mine to half, and it's still functional.

Before

After

KMPlayer,GOM player,ALShow have codecs already installed

for real video format,get the real alternative codec

I and everyone i work with uses VLC, it's pretty good.

try jetAudio

i am using vlc it works fine
