Query: It's not as simple as it sounds

I purchased this product to control my home theater components that are hidden away in a closet. I have a pretty complicated set-up, that includes a video switcher and multiple components. The included software CD seems to program the remote pretty easily (works on a Mac or PC) but after everything is programmed, it just wouldn't work. It's one of those things you would need to mess with for a couple of 8 hour days to get everything timed and working right. I never called Tech Support, I just sent it back and gave up. I ended up going with the Next Generation Remote Extender - it's about $30 on Amazon and I highly recommend it if you just need to control components that are not within line of sight.
