With the older models I could rename the default "My Slingbox" to something more descriptive like "Bedroom TV" and "Downstairs TiVo". I don't see any option to rename the Slingbox 500 from the web or the device itself.
Hello, I no nothing about older models. Using a Songbox500, I go to the "Watch" page; then I go to "Settings" then, on the right side below the Live box, I clicked the EDIT button and was able to change the Name. Hope that helps.
