But before fixing an error, understanding why it happens is crucial. There are various reasons why your video file won’t play, such as file corruption, virus attack, file compatibility issues, faulty sectors in hard disk, or software issues. Let’s see some manual fixes for common video file errors.

Common Video Errors and their Solutions

Some most common errors that users face while playing video files include:

1.  “Windows Media Player is unable to play the file”

2.  Codec Errors

Codec is a proprietary software that compresses and decompresses digital videos to maintain the quality of video files. Sometimes, you face problems, like the file you’re trying to play isn’t compatible with the codec of your laptop. This can cause issues, like the “video not playing”.


A video codec pack can assist you in handling problems caused by incompatible video and audio formats. You can either set Windows Media Player to download codec automatically or download a pack from the Microsoft Store. K-Lite Codec Pack, X Codec Pack, Shark007X Codec Pack, and others are some of the popular video codec packs you can download for Windows 10.

This is a little different from other typical errors but it’s still an error to be aware of. It is quite likely for users to face a display error but often, people report distorted audio errors too that tend to hinder a video’s playback.


This problem generally occurs due to corruption in the video file. There is no method to manually fix sound problems in your video files. You need to use Stellar Repair for Video to fix corrupted or damaged video files.

  2. Verify if your display and audio drivers are up-to-date. If not, download and install the most recent versions.
  3. Attempt to view your videos with a different media player.
  4. Reduce the size and resolution of the video.

6.  SD Card

It’s very common for media files to get corrupted when stored in SD cards. Transferring these corrupted files from the card to your laptop may cause problems when you try to open them in Windows Media player or QuickTime player.
