you can 'see' it by unplugging your DVRs and recording a short show in progress like TVLand. Once it is completed, plug back in DVR and check recordings. When you play back what you recorded while the DVR(s) was unplugged the status bar will show the cloud symbol, and if you have on the comcast labs transport bar the cloud symbol will be in upper left corner.
edit:" by record i mean run the TV app and hit record on a live program on for example TVLand.
