I have always been able to view the YouTube vids that I downloaded. Starting this past week I have downloaded several videos that will NOT open in any of my players. All players are updated but the files still will not play. The file type says MP4 but I have my doubts as to if that is what it really is. I use the videos when not connected to the internet to teach firefighting strategies and tactics so nothing illegal or unethical here.
I TRIED THIS WITHOUT SUCCESS:
Why can't I play the .mp4 file I downloaded?
We are aware of a compatibility issue that is 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 is being misidentified as MP4.
We are working toward compatibility with this new format.
To check if a file is a true MP4 file or the new format, try playing the file in QuickTime.
If the file does not play in QuickTime: Try Solution 1 below.
If the file plays in QuickTime: It is a true MP4 video and should also work in RealPlayer. If it doesn't, try Solution 2 below.
The following steps should work for customers who are on Windows 7 or 8 and are using Internet Explorer (version 9 or higher) to download videos.
1. Click the Tools (gear) icon at the top right of the browser and select Manage Add-ons.
2. Under Adobe Systems, click on "Shockwave Flash Object" and click the Disable button that appears at the bottom right of the window.
3. Close the Manage Add-ons window.
4. Go to www.youtube.com.
5. It will prompt you to "Upgrade Adobe Flash Player"--ignore this message.
6. Try downloading a video. It should successfully download and play in RealPlayer.
If you have RealPlayer 16 Plus and are still unable to play .mp4 files that work in QuickTime, try the following steps:
1. Make sure you are signed in to RealPlayer Plus.
2. Make sure all updates are installed to RealPlayer Plus (click the RealPlayer logo and click Check for Update, or sign out and sign back in).
3. Update QuickTime Player (visit Apple's QuickTime site to download).
4. Re-download the .mp4 file. Note: Some files created with camcorders may not play in RealPlayer
