Thanks for using the Slingbox Answer Forum. We understand that you are having an issue using the Logitech Revue on screen remote. One thing that may help is to check the bandwidth, because the Logitech Revue has bandwidth requirements of 2 Mbps or higher for High Definition, and 600 Kbps or higher for Standard Definition. Also, below is an article for using Sling Remote.
Hopefully this will help,
