I have everything working on all components except for one annoying thing. On my DVR's remote there is a button labeled "list" which shows what you have recorded. Is there a button on the 670 for that? Can I make one of the buttons do that? I have tried, searched and experimented. I am lost, but happy since 99% of everything works.

I don't know if there's a specific button labeled "List" on the 670, but why don't you just add it to the LCD button in the Watch TV Activity?

There isn't a button that corresponds to LIST or recorded material on the 670. I have looked at learning new commnds but I have nort been successful. I am sure it is one of those things that when you see someone do it you go AAAHHHHhhhh...

When you say you haven't been sucessful learning the command, did the Logitech website tell you that it didn't learn the command successfully? If it did learn it, but you can't find the command, that's easy. Any learned commands always appear at the bottom of the drop down list.

If you are having trouble learning the command, try adjusting the the distance between the remotes. 1.0", 1.5", 2.0", etc.

I just mapped my Menu button to the List command in the software, and all is now right in the world. Or, do like someone else said, and stick it on the LCD.

To control our Tivo with my 670, I mapped the Stop button to the List (Now Playing) feature. I mapped Menu to bring up the main menu.

I've been doing it that way since our MX-500, so Im' used to the stop button working that way. :)

Can you reassign a different button for it?

I have had a 6412 and a 6416. In the Logitech database, the command is not called "List", its called "MyDVR", which is what it was called on the 6412 silver remote. You should be able to find it in the pulldown choices.
I use that a lot as well, so I have it on my LCD and on "Prev", which I don't use. I thought about putting it on Menu or Info, but I kind of like to use those sometimes.
I've got a 550.
