Problem with Windows Media Player Classic and the LAV Codec

Hi there!
I use the Media Player Classic as the Main Videoplayer on my System and I have a problem with my LAV Codec. I have a video format (.mp4) which i can't read completely in the Media Player Classic. I have no picture but I have a perfect Sound. The thing I do not understand, is that the Videofile is reading by the Windows Media Play without no Problems. There is Sound and Video and on my Taskbar there open the Filter LAV Video Decoder (2x), LAV Sound Decoder (2x) and LAV Splitter (2x).

So I think i have all Filters I need, but how I Can use it in my Media Player Classic?

Sorry for my bad english, I hope you understand me.

My System :
System: Windows 7 Ultimate 64 Bit
CPU: Intel Core i7 - 3770K 3.50 GHz
RAM: 32 GB
GPU: AMD Radeon HD 7800
K-Lite Codec Pack: K-Lite_Codec_Pack_1165_Basic

First update to the latest version (11.9.6).

It works

I'm sorry that I did not come himself about it.

Thank you for your help Admin. Wish you all the best!!
