[quote="tclotworthy"]Hi, I don't believe rokudale is correct. even restarting the roku device and re-entering the roku media server does not result in the cache clearing, at least not with my Roku 2[/quote]
Roku doesn't make a Media Server. The Roku Media Player is a client. There is no persistent storage of the contents of any DLNA Media Server in the RMP except during the running of the RMP. When the RMP is exited it is all expunged. Also when you are back in the "select Media Source Screen" the cache is cleared. If you are seeing stale stuff after first entering the RMP, it is because the Media Server on your PC itself has stale or incorrect data.
You can notice this yourself by timing the difference it takes to enter a folder the first time, and then every time after that. The first time will be the longest. If you are running windows 7 you can start up Windows Task Manager, then click on Resource Monitor. This will bring up a set of graphs. Watch the 'network' one and you can see the amount of data being pulled.
