SD card might be causing Note 4 issues.  How can I fix?
I am thinking to back it up to my pc, reformat the card, and then put the files back on.  
But what if there's a bad file or corruption?
What tools are there to fix it/scan it?
Thank you,
Mark

If there's a bad file or corruption, you will know it.
First backup it indeed. Format is also ok. After that, do a full scan (Properties ,Tools, Error scanning, enable all checkboxes).
If that comes out clean, use it again in the phone (try to restore only needed files, like pics etc. Don't fully copy everything. Strange long file names or temp files can sometimes cause Android to act crazy)..

According to XDA forum, it is better to format from the phone itself.

http://forum.xda-developers.com/note-4-att/help/exfat-support-micro-sd-t2906740

You can try to format from PC but you need to choose the format of exFAT.

My experience tells me that if you want better compatibility, format from the phone is a better choice.

How large is the mp4 file?

Q1. Can you play other mp4 file you download from the Internet?

Q2. Can you play the problem mp4 file using VLC player?

VLC for Windows

If Q1 is Yes and Q2 is No, It seems to me that your microsSD card is corrupted.
