Read the description: "Advanced IR Repeater system allows you to Control Home Theater Components Located behind Cabinet Doors. We have already upgraded this unit to a Dual Frequency IR Receiver
Obviously the issue is a real one...
I totally agree dual band issues are something one needs to be aware of when troubleshooting. I'm sorry I didn't make myself clear.
I'm not disputing dual band issues in general. But IN THIS CASE, the OP has a cable box model that has been around nearly 10 years that uses the General Instruments protocol which is most definitely 38.4kHz, the most common IR frequency, which is universally compatible. There is absolutely no reason any IR repeater or Next Gen shouldn't work. The OP's problem is an incompatibility with his remote and Next Gen, improper setup, or environmental factors, not a dual band issue.
I've had this very cable box in the past and used it with several remotes and repeaters without issue.
