I just changed my cable boxes from dvr to whole home dvr from cox, and the system is not worth the money. My worst complaint is recording sports.
When you open the guide and look for football, none of the information is programed. The guide does not list the teams playing, just the location.
I have missed so many games because you can't determine who is playing. Don't upgrade to whole home dvr, the regular dvr box allows you to search by theme (football), and you can see all the games and record easily.
Also the cox customer service is no help.
