I realize the original post is 2 years old, but this may help someone else who is currently looking for answers.
aviewer has done his usual excellent job in providing in-depth information. I'll add my two cents to this question, based on my own (School of Hard Knocks) experience. ;-)
I can confirm that the Logitech Harmony 650 remote WILL work with UVerse cable boxes (specifically, it works with the VIP2250 STB/DVR box and the VIP1200 cable box). I have a total of 5 TV's in the house. One is connected to a VIP2250, and the other 4 are connected to VIP1200 boxes.
In most cases, when it comes to remote control compatibility with a particular component, the issue is the codes: i.e., does the device support (or can it learn) the codes used by the component?
The VIP series boxes add another wrinkle. The VIP boxes use a "special" IR protocol developed by Phillips known as RC-MM (Remote Control - Multi Media). This protocol has more exacting timing requirements than conventional IR protocols. Therefore, in order to work with the box, a remote has to support not only the required codes, but also must be able to faithfully reproduce the required RCMM protocol. Otherwise, the VIP box will simply not respond at all (or in some cases, may misinterpret commands).
Again, the Logitech Harmony satisfies both requirements, but not all remotes advertised as "universal" do.
As a side note, because of the RC-MM IR protocol used by VIP boxes, other devices, such as the popular IR-over-HDMI extenders, will not work, either (owing to the fact that the required IR protocol cannot be faithfully reproduced).
In short, working with the VIP series of boxes can be frustrating, and requires some patience and a good deal of research to find workable remote control solutions!
