Cloud Based DVR

Recently my DVR that is cloud based recordings started to jumble, we have missed several different shows on different networks.  Shows will jump skip sound is not there and the show will jump to the beginning of the program even though you are actually 45 minutes into the program.  When I fast forward you can see what the program should be showing but when you press play it is back to previous see stuff.  This is very frustrating and missing shows is maddening.  I have tried to watch the missed shows on demand but some aren't there. 

So why is this happening, COX? What can be done to fix this?
