i need to control a 70" sharp quattron, and a motorola dct 6200 STB (hidden in closet).
bought the nexgen remote extender, doesn't work for either device. Will getting a universal remote work? which one? looking to spend least amount of money. No need for macros or anything.
You might be running into the dreaded 'dual-band IR' issues that plague most everyone in the North East / NY area. I know people who disagree with this comment but take a quick look at the front of the provided remote... all of my Scientific Atlanta ones have two IRs side by side and refuse to work with 100% of the monoprice HDMI+IR over cat6 solutions...
It's quite disappointing .. They've known about the dual-band ir issues for going on a year or more ... I think tivos or maybe directv boxes also have dal band IR ... On some models and we're all SOL if we buy their otherwise great stuff.
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.
