I'm not able to play a video on windows 2003 :-( I installed every well known codec packages on internet without luck.

I'm trying to play it with the divx player.

I have no image and no sound. It plays but wihout showing anything but this message

This file contains a track in the AAC (advanced audio coding)(code "255") format. You may need to install a directshow decoder for this audio format...

I tried CoreAAC-1.2.0.573 in relation this error msg, but no luck.

Could you tell me which codecs I have to install?

might help to mention which codecs you installed – Journeyman Geek Jul 19 '10 at 3:03
    
Does the video play on other systems running different OSes? – alex Aug 28 '10 at 19:05

VLC might do the trick- since it has its own internal codecs, supporting everything and the kitchen sink. If you need WMP support, CCCP is a good bet, but since you mentioned installing every well known codec package, i assume you tried that ;)

Thanks for your answer. I'd need to install system-wide codecs instead of a magic player :-) I'm develeloping an application in c# that need to access the video and it can't because missed codecs. Installed packages: ffdshow, MatroskaPack, DivX, CoreAAC, ac3filter, K-Lite. – StackOverflower Jul 19 '10 at 13:13
    
give cccp a shot then - it should let you handle mp4/aac videos i believe – Journeyman Geek Jul 19 '10 at 23:48

Have you enabled Hardware Acceleration? On Windows 2003, this is disabled by default.

Control Panel -> Display -> Advanced -> Troubleshooting

The slider is all the way to the left by default (None), drag it all the way to the right (Full).
