[QUOTE="stephenv, post: 1054688, member: 145465"] I can now report success with the IRSS through USB-IIRT to control two set top boxes for two Hauppauge Colossus cards. As suggested elsewhere I did try to use a digital camera to look for the IR LED activity during blasting. This worked, but the only indication of activity was on the main part (the box) of the USB-IIRT device. But I could not see any activity from the two external blaster cables that came with the set top boxes I have. So I'm thinking these are actually receivers - not transmitters. Next, I followed a suggestion from an old post on the USB-IIRT forums, use a pair of head phones to listen for activity. This worked, but showed the following: 1. port 1 blasts to the right headphone 2. port 2 blasts to the left 3. port 3 blasts to the main box one would think that port 1 would be the main box... Then I went digging through my old cables boxes and found another blaster from some other PVR device. This actually worked and I was finally able to see IR activity on the extra blaster cable with my digital camera. Then I took a closer look at the two set top boxes (Motorola DCX3200-M HD Receivers that Shaw Cable uses) to see where the IR receiver was. By shining a strong flashlight at the front panel you can make out a small area to the right of the clock display where the receiver is. I then started testing different code settings for the IR control (since my STB is not listed in the TV3 Blaster Plugin for IR Server). I found that the Motorola DCT-6200 settings worked and after taping the two blasters to the front of the two STBs I got my first dual channel tuning to happen. [/QUOTE]
