Currently if you set Media.trackVars in a video, it will only send data for the first server call from the video, when it starts playing. Any additional calls, such as with the milestones or X number of seconds, will not have the data outlined in the Media.trackVars sent with it. My request is that all variables specified in Media.trackVars and Media.trackEvents are sent with every media request without having to do this using Media.monitor. This would not only make sense, but make implementing much easier.
