Query: Not Ready for Prime Time

I ended up returning the Harmony 890 for a refund. It almost did everything I needed, but it could not do one critical task that made it useless. What it could not do was select the proper video inputs on my Samsung DLP bigscreen. So, I still had to do this manually (using the Samsung remote -- thus defeating the purpose of buying a universal programmable remote).An email to Logitech asking for help elicited no response. None. I was pretty surprised. I am fairly technical and I could see in the program listing of internal commands that the unit was sending out the wrong command. But, for the life of me, I couldn't figure out how to go in and change it. So, I emailed support. And, never heard anything back.I had high hopes for this product. I rarely return products -- usually I can get them to do want what I want. But, in this case, I gave up and just returned it.
