Possible reasons of color bars in the Cinegy Air Control preview may be the following:

• The file is no longer available (has been moved or deleted). In this case try to re-insert the file to the playlist.
• The file is not accessible by the user account under which Cinegy Air Engine is running.
• If the Cinegy Air Engine is running on a separate station, make sure the file is added to the playlist from the shared folder, but not from a local folder.
• If nothing from the above matches your case, try to play back this file in the Cinegy player and check if it can be played successfully – probably you will need to install an additional decoder to decode the specific video format.
