I have this Philips Remote - have been using it for 5 months or so. All I ask it to do (in regards to the 990) is change inputs and volume, and it does this fine.

My only minor problem with this remote is that it has seemed to develop a minor lag. Sometimes it takes a few seconds to register a command. Usually this is not a problem but there have been a few times where I have been pressing volume up and the next thing I know the volume on the 990 is skyrocketing - it's almost like the volume up command is being continuously sent.

To be fair, this has only really bothered me on 1 occasion. The other times, the volume usually goes a few clicks higher than I'd like - at most 10 notches. On one occasion, it went up about 45 notches.

For simple commands such as switching inputs and volume, this remote works well. I enjoy the 'activity' based aspect of it (setup was pretty painless), although I don't think it is as configurable as other universal remotes.

I have setup activities to:
1)Watch Xbox360
2)Watch DVD
3)Watch DVD (this turns on my digital media player)
4)Watch PVR
5)Listen to CD

2 clicks on the remote does all of the necessary switching to perform the relevant task.

Hope this helps.
