At times, you may have experienced issues where, when you have played a video on your Windows PC, the video may start to freeze or lag. Most of the times, such issues are caused by a bad or corrupted Codec Packs or Device Drivers. Let me suggest a few fixes which can help you resolve such issues.
Issues with Codec Packs:
The main problem I have seen in most of the cases happens due to installing different codec pack which might create conflicts. For example when you install VLC Code pack or maybe the K-Lite Codec pack, the Codec version may be different resulting in playback issues.
Then first thing I would recommend to do is to uninstall all the Codec packs like K-Lite Codec pack, Media player classic, VLC and MPC Star.
After uninstalling all the Codec packs, reboot the System. Then run Windows Media Player troubleshooting packs to make sure the native Codec is intact. Use this Guide. If required, run the Fix WMP Tool mentioned in that article.
Once you have completed that process then reboot the System again.
Next, download Shark007’s Codec Pack for Windows 7.
These are Windows Media Play Codecs and that’s all you need to play almost all the formats.
The Codec pack contains a Settings Application, to be used in conjunction with your Windows Media Center setup. This which will enable each user to choose different splitters and decoders for specific file types. The application will also allow you to choose from 10 different speaker configurations from ‘same as input’ and all the way up to full 7.1 channel output.
Display Driver Issues:
Sometime the playback issues can cause by an out-dated or corrupted display or graphic drivers. Check if you have Display Drivers in Device Manager.
Go to Start and under search, type in Device Manager and hit Enter.
There expand “Display Adapter” and see if you have a Yellow exclamation mark. If it exists, it means that Display drivers hasn’t properly installed.
Go to the manufacture’s website and download the appropriate drivers and install it. Once you install the Drivers reboot the System and test you Video Playback.
