So recently I installed 'HTML5 Video' onto my website and converted a video that was exported as a HD720 p30 .wma to both a .mp4 and a .ogt? (For the program I used to convert I used Real Player and the thought maybe something was causing the issue with that so I tried Miro Video Converter) however, upon trying to upload both files through HTML5 I received the message saying 'INVALID FILE EXTENSION.' I also tried a different add-on, but alas the same issue arose and I am just trying to figure out what could possibly be causing this not to work correctly.

Specifications:

Concrete5 version 5.6.0.2
