Newer MOV files should play without any issues, but some older MOV files might require additional codecs.
If you try to play an MOV file that requires an additional codec, the Codec Finder window will pop up and inform you that you’re missing the necessary codecs to watch the video.
If you click the “Search for Codec” button, you’ll be taken to a page where you can download the codec you require.
After you install this codec, turn off GOM Player's internal MOV codec by following the steps below:
1. Launch GOM Media Player
2. Open the Preferences window (push [F5])
3. Select "Filter" from the list on the left
4. Go to the "Source Filter" tab
5. Under "Source Filter Control", scroll to the bottom of the list and uncheck the box next to "QuickTime Video (.mov .3gp .k3g ...)
6. Try to play the file again
