Great, simple, plug in. I have an issue though. On the site I have the video displayed in a very small frame ~ 280 x 160, on the assumption that 90% of people if they are interested will open in full screen after the first 10 seconds. The problem is that because the starting frame size is so small, the resolution is appalling for the first 30 or more seconds while it auto adjusts. the video is only 2 minutes long so this is a chunk of overall view time.
It seems YouTube will allow a force of larger resolution simply by putting
?vq=large at the end of the URL. But your plugin (or WordPress) strips this out. Any advice on how to achieve this?
