Why can't I play the .mp4 file I downloaded?

A compatibility issue was preventing some .mp4 files from playing in RealPlayer. Essentially, the files that are being downloaded are not actually MP4s but a new streaming format that was being misidentified as MP4.

This issue has been fixed in the latest build of RealPlayer 16, released on August 21.

If you are currently using RealPlayer Plus 16 or the free version: Please open RealPlayer, click the RealPlayer logo in the upper left, and select Check for Update. You will then be able to update your RealPlayer to the newest build. Please note that you may need to re-enable the RealDownloader extension in your web browser as well.

If you are currently using RealPlayer Plus 15: Please contact Customer Support for additional instructions.

After updating RealPlayer, please re-download the videos that previously received the "General Error" message.

Note: Some files created with camcorders may not play in RealPlayer.
