I’m having this problem. I have a macbook air OS X and I got WD MyCloud for christmas.
All files like .mp4 and .mkv and .avi play on my DLNA for my Samsung TV and my Nexus 4 phone.
THE PROBLEM IS when i open up WD MyCloud on my mac, it wont open or play .avi files. Perhaps it has something to do with VLC? I downloaded the latest version of VLC.
This is my first mac, im normally a windows guy, I know about codec, I edit videos. However, im NEW to mac.
So how do I fix the problem to be able to play all files on my Mac OS X?
P.S. - I downloaded all the files to my mac, then uploaded them to WD MyCould for storage purposes, they played just fine on my mac before I put them on WD MyCloud.
