emann, did you copy the first setup to make the second? It does sound like you didn't punch through the volume and it's still trying to use the volume for the surround system instead.

It's been a while since I programmed a URC remote, but this was pretty straight forward when I was doing MX-700 and MX-850.

You might want to look for the controls to turn on/off the speakers on the TV and then include that in your ON/Off macros to avoid having the TV speaker on when using the surround system. Alternately you can lower the volume all the way down to zero - which means a lot of code repeating (since you won't know where the volume is originally you'd better include some extra volume down repeats).
