fault description - video?

Has anyone out there regularly requested a video of fault  
behavior as a precondition for issuing repair RMAs?

I've sent verbal descriptions, meter readings and scope  
waveform captures, only to be met with a request for  
a video - in situations where there are no moving  
parts (meter or oscilloscope), or where movement is easily  
described as full travel forward 360deg, center, full travel  
recverse 360deg (servo drive).  

What is this?

I will answer with an analogy:

We have a cat, which when it was two years old, very suddenly and without a
ny prior warning, started to stumble, tilt its head to one side and walk in
to things. We called our vet to bring him in (this was at night), and from  
the verbal description, they thought it was some sort of stroke or similar  
neurological issue - and referred us to a much more distant emergency clini
c. We arrive at the clinic about 40 minutes later (flying low all the way).
 The vet there takes one look at him walking and says: "Bladder blockage".  
Which is what it was. He is fine now. But if he were treated for stroke, ev
en for a couple of hours, he would be dead.

Not sure, but I would often request pictures so that I could verify  
the set-up.  (A picture of a 'scope trace can tell you a lot more  
than a reported amplitude.)  Maybe pics would be enough?

Scope screen shots, annotated and sequenced using their component  
and test point markings - requests for other significant monitory  
positions - were ignored.  

"Would there be a possibility to provide us a video of the issue?
This would be more than helpful for us to identify the cause for  
the malfunction and it would give us the chance to initiate the  
further procedure right away, also we will have to save the defect  
in our database."

They have a database of videos?

In some cases, I guess there is a language barrier, or I was  
communicating with the wrong guy (sales).
