First of all, I've looked up and down on the net for a solution for the problem with the ir utility not working. I've given up on that and are now focusing on getting both of my cards working. Right now I have to disable both tuners on the 500mce card in order for me to view or record programs. If I even have one tuner enabled on the 500 with the 350 enabled the computer locks up and I have to force a reboot. I've tried updating the drivers and the software. Any help?
