How to Fix QuickTime Error -2048by Aaron Parson
To play MPEG-2 content using QuickTime for Windows, you need the QuickTime MPEG-2 Playback Component, a commercial add-on. If you bought the component but receive error -2048 when trying to play a video, you need to update the add-on to the newest version. QuickTime for Mac OS X does not require the MPEG-2 component as long as you have OS X Lion or a newer version of the operating system.
Updating the Playback Component
After updating QuickTime for Windows to version 7.6 or later, you need to also update your QuickTime MPEG-2 Playback Component in order to avoid error -2048. Visit the "Your Account" page on the Apple Store (link in Resources), click "View Order History" and log in with your Apple ID. If you don't see your order listed, change the purchase period using the drop-down menu. Open the order to download the new version. If you bought the component several years ago and it no longer appears in your order history, contact Apple Support to receive the update.
Applicable File Types
Error -2048 occurs when QuickTime attempts to play video files that require the MPEG-2 component. Most MPEG-2 videos use the MPG or MPEG extension, but these extensions can also indicate other versions such as MPEG-1 that don't require the component. The component also allows you to play back non-encrypted DVDs, but not those with copy protection. All other types of files that open in QuickTime will continue to work without updating the MPEG-2 component.
