Some of the videos on my forum are going to be hosted on YouTube. With those videos, I understand that you can add "&ap=%2526fmt%3D22" to the end of the embed link to force an HD playback. When I add that code to the end of the link, it just simply does nothing. Anyone know this trick for forcing back a HD play in Xenforo?
hd Values: 0 or 1. Default is 0. Setting to 1 enables HD playback by default. This has no effect on the Chromeless Player. This also has no effect if an HD version of the video is not available. If you enable this option, keep in mind that users with a slower connection may have an sub-optimal experience unless they turn off HD. You should ensure your player is large enough to display the video in its native resolution.
