Recently I'm not able to use my Logitech Revue Keyboard to control the DVR while copying video from the DVR to the Ext. Harddrive. The keyboard still controls all the googletv functions but will not control the DVR functions while copying from the dvr to the ext. drive. As soon as the copying is finished, everything starts working again. Has anyone else experienced this or have any ideas? My standard remote still works fine all the time. I also can see the light on the revue flash when it receives a signal from the keyboard but the satellite receiver does not respond.
