I need to play back my light cues according to the video content, synchro with the sound in the video.

How to:

1. upload a video and able to play back and hear the sound in capture (without hearing the sound. I do not know the cue point).

2. how to control the start and stop and pause of the video on the fly? (without going to the property) I need to make the screen ready,   play the video and then i will be busy triggering cues on the console.
