I purchased a Roamio 3 weeks ago and have spent hours on the phone with TiVo support concerning the black screen issue. Do they not know about this bug? They had me jumping through hoops including countless calls to Charter support, three charter support visits to my house (fourth scheduled tomorrow) and a TiVo box swap. Finding that this is a known issue is incredibly disappointing and infuriating. The TiVo support team should have told me about this software bug in their box and instead, has wasted my time. They are no better than the crooks as Charter. Boxing my TiVo boxes up and sending them back... What a waste of my time.
