Increasing "Recently Added Movies" size?

I'm trying to increase the the size of the "Recently Added Movies" queue size. I have done some searching here and have created the below "advancedsettings.xml" file in my Win 64 htpc, C:\Users\acer\AppData\Roaming\XBMC\userdata. I'm using Frodo Beta 1.

However, the "recently added movie" queue size did not increase after I restarted XBMC. Can somebody tell me why this didn't work?
