Clear iPad Cache of Shared Library

Does anyone know how to clear the cache of iTunes Home Sharing on the iPad? I'm making changes to the sorting of my shared TV Shows and I cannot get the ipad to show my changes. The only way I can figure out is if I restore the device and then connect to home sharing. I've tried restarting the device, the pc, clearing cache content from itunes folder... No luck. Any ideas? Shouldn't iTunes have a clear cache button that tells the devices to re-download all the info about the files?
