Hi, looks like the Meteor Slides plugin may be interfering with Viper's Video Quicktags plugin? I deactivated all plugins but Meteor Slides and the YouTube video plays fine. When I activate Meteor Slides, the YouTube video only displays a still and then links externally to YouTube to play the video. This thread below might explain it more specifically? Can you help? Running WP 3.3, BP 1.5.2.
