Windows 7: How do you get two IR blaster cables to work?

How do you get two IR blaster cables to work?


First let me give some details of my hardware configuration. My OS is Windows 7 Home 64 Bit. I have two TV tuners, one is a Hauppauge HVR 2250 and the other is the original tuner that came with my HP 9300ct computer. I have an IR blaster kit that I bought from Hauppage ( link: Hauppauge Computer Works Web Store ).

I have Comcast digital cable and my goal is to use my tuners to be able to record two channels simultaneously. I have two cable boxes (DTAs, to be precise) and two ir blasters. The back of the IR receiver from Hauppauge has two ports so this is where I have connected the two IR blasters which attach to the cable boxes. I am able to receive cable TV just fine from both tuners. The issue is that Windows Media Center can only change the channel on one of the cable boxes. I have checked that both ir blaster cables work when they are plugged in individually, but they do not work together. Does anyone know what might be the reason?

Many thanks!
