I developed my own videoplayer plugin since I needed some additional features. This plugin seems to working ok both as plugin and as regular hotspot. However if I use distortion (distorted = true) the video is no longer displayed, but the audio is working fine.
I put an example on http://www.uxperiment.com/krpano/test.html to illustrate the various cases (please excuse the fact that both videos start playing which is kind of noisy).
Any clues why the videoplayer is no longer displayed are welcome. Thanks!
