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? chris Christoph Willing +61 7 3365 8316 QCIF Access Grid Manager University of Queensland
