I just got my Vizio VTAB a few days ago. The Remote Control app is terrible. I had a long conversation with a Vizio tech support person who admitted the problems. He also told me that a major update was in the works that would solve many of the problems I raised. Whether or not that will include learning he didn't know or wouldn't say. What got me was that, although every device I have is in the database, most of the screen layouts did not provide what is needed to operate the device! What is needed is a PC-based editor that will allow for customizing screens, implementing macros, etc. No technical reasons that I can see that would preclude doing this. It would make the VTAB competitive with the $2000 - $3000 devices by Crestron, URC and others.
