Cox cloud dvr horrible

Cloud DVR requires a strong signal.  Yours is probably too weak for quality playback.  I would suggest you call Cox and schedule a tech visit to check your signal.  If your dropline comes in from a pole, be sure to specify the tech must have a long ladder and, when he arrives, request your signal be checked at the tap (Cox equipment that connects your dropline to the Cox main line).  If a signal issue is occurring on Cox's side up to and including the demarcation point (box on the side of your house), you won't be charged for the tech visit.  You might want to subscribe to Cox Complete Care ($10/month) prior to scheduling the tech visit because it will cover the fee, regardless of where an issue occurs.  You may cancel CCC after 90 days.  If you cancel before then, you'll be charged any fees that were waived.  But Cloud DVR seems to have a lot of issues.  It might be worthwhile to keep CCC and schedule a tech whenever an issue occurs, at least until you go an extended period with no issue.  I'm not a Cox employee.  I'm just telling you what I'd do.
