Up for an investigation? We've got a curious case going on with a recent FCC filing, which sees the user manual of the recently unveiled DuoDVR ViP 922 (yeah, the SlingLoaded one) alongside images of a heretofore unseen ViP 822 DVR. Curiously, the actual FCC label corresponds with the "922," through the logo on the pictured Sling DVR definitely shows "822." So, is this just the typical step a device takes before it hits shelves in America, or is this a DVR we've never seen before? Something tells us it's far less exciting than our imaginations are leading us to believe.
