[AG-TECH] iTuner 4 port BT878 card

[Michael Miller]

Bob,

I have seen exactly this behavior.  I have only 2 cameras so the problem is 
somewhat simpler than what you have.  When I close out my vics, whichever 
camera was last being used will come up as the default choice in the 
dropdown list.  But, one vic has already chosen this vic and I need to 
choose the other camera for this vic.

So, you can run your client and 3 dialogs will come up each with camera C 
as the default choice.  Don't pick that one, pick a different one, say 
camera D, then on the next dialog, pick E and so forth.

The first time you run the vics, there may not be a camera chosen by 
default so you'll get 4 dialogs.  The trick is to be sure that you choose a 
different camera for each vic.  Some drivers like the Logitech Quickcam Pro 
4000 make this difficult because the streams are not numbered.

This occurs because vic doesn't support the Window Driver Model so you 
can't tell vic to pick a stream by default and have it stick...

Hope this helps
