Can't play HyperCam video error message on Windows 8.1
"When I record my screen and try and play it back, I get an error “Can't play. This item was encoded in a format that’s not supported”. I have Windows 8.1. It is trying to run the video in Xbox video for some reason."
Apparently XBOX video player is registered as the default program to play video files, and it does not know how to play the AVI video format. Right-click the recorded AVI file, choose “Open with…” from the menu, and choose Windows Media Player. It plays it fine, just tested on Windows 8.1.
