Once you have dropped the file onto the appropriate device it will begin conversion:
When the file has finished conversion, click on the appropriate device name under the Devices column. From here, click the Open iTunes button to open the iTunes application.
Your files will be added to iTunes under a new uTorrent playlist. In iTunes 11, check under the Movies
