How do I clearly distinguish between:

 - Moving images **only**
 - Moving images and audio

Using as few words as possible, without it sounding 'awkward' of course.

> **Black Hat Guy:**   "I was watching and listening to this moving image with audio data stream on my LCD screen and speakers respectively about..."
> 
> **Mrs. Roberts:**      "You were *what?*"
> 
> **Black Hat Guy:**   "I was watching a video on my computer about..."

For both technical and non-technical usage?
