DVR intermittently not recording tv shows or series

I am having issues with DVR recordings whether I choose to record single TV shows or choose to record a series.  When I look back through what I have scheduled, many recordings say "fail" - these are shows I have been recording successfully for years such as all Red Sox games and all M*A*S*H episodes.  This past weekend channel 1190/Catchy Comedy had The Monkees on all weekend and I have tried unsuccessfully all weekend to record the series, single shows, etc. and none of them recorded.  I spent hours and hours online on automated chat and then on the phone and this issue has not been resolved.  It's very frustrating to pay $249/mo and not have all of the services you are paying for, then spend hours and hours online and on the phone with no resolution.
