Ghost in the TV studio

I've never seen this show before. Just got the DVD. If this has been pointed out on another thread let me know. In the darkened scene where they are playing the audio tape, a ghost appears to the right of the female character. Creepy. I saw it (had to rewind to be sure) and was waiting for the easy plot device of some "viewer" like me discovering it and calling in to the ghostline letting them know the studio itself was haunted. Did anyone else see this ghost? If this ghost was real but not exploited further in the teleplay, I have real respect for the creative team behind GhostWatch.
