Hi,

I'm about to throw my computer at the window. I've been trying to read video files for two weeks, have tried everything I found on the net, nothing is working. Absolutly no video files are working (sound is ok). Name the extension and the codec, it just doesn't work. It was working fine and I can't find when it started to not work. Maybe when installed the new drivers and multimedia thing of my ATI Radeon 9800, I don't know.

For me, codec is indeed hell. It's like a jungle and I'm pretty sure my computer is right in the middle of this jungle right now. I read the Guide on this site, uninstalled everything and reinstalled what was mentionned, in order. Didn't work.

Is there any tools that can wipe out EVERY codec and filter? Except a HDD format of course, which I'm trying to avoid.

Please help me!
Thanks in advance.

With the K-Lite Codec Tweak Tool you can generate a full list of all installed codecs and filters. It also allows you to exclude the ones belonging to Windows (which you obviously want to keep).

Instructions for removing codecs and filters can be found in the K-Lite FAQ in troubleshouting section.

However, simply removing everything is not the best solution for your problem.

Use Media Player Classic. That will show you an error if a decoder is missing. If it doesn't show any errors, then look in it menu under Play -> Filters. There it show exactly which filters it is using.

Thanks a lot for your answer. I'll try what you said tonight.

I found the problem. My codecs are working. The problem has indeed started when I installed the latest drivers of my ATI video card. For some reason they putted the Contrast and Saturation settings of Catalyst Control Center to 0 so everything was showing black.

Lost almost a week on this. So people, check your video card settings for the overlay options.
