Porfirio,

It looks like a hardware issue - your cards are recognised but not  
enabled by the operating system, so AG software won't detect them. Is  
any other (non-AG) software able to use video from these cards?

Since the problem appears to be at the system level - some IRQ sharing  
issue - I would first try with only 1 capture card installed. You may  
also have to move the card(s) to different slots and look for  
differences in behaviour.


You mention that you've just upgraded your system - did you have AG  
software installed and running on the previous system with this same  
hardware combination?
