Cool.  Like I said, it was a long shot :P

Ah, yes, that is what I was thinking about....I ran out of time last 
night to try to track it down to see if it might have pertained to your

Sorry, I don't know.

Actually, that's an interesting comment.  I may be able to aide in 
expediting your rate of correspondence with Dvico.  You see -->  Not too 
long ago, someone on AVS made a very similar statement.  Another poster 
then replied that they had no problem with more or less overnight 
correspondence with Dvico and then provided a email link with which they 
used to correspond.  The original poster then followed up stating that 
he had just tried this updated email address and Dvico had indeed 
quickly responded!

Now, of course, those messages are likely going to be buried deep in one 
of the many Dvico threads....but, I believe Terry Peterson now has a 
line of dialogue with the Dvico, so I will ask him....I will update when 
I hear back from him.

I looked at the picture in product brief
