Cox has put DRM on all channels in Tulsa AGAIN

Six months ago,  my Silicon Dust  home Run stopped working on most channels because COX had suddenly  flagged all channels with DRM except the locals

A week after I queried  this, things  went  back to normal.  Now it's happened again.  This is very frustrating.   I can't see that its official policy because, if it was, they wouldn't change them back?

 But if its not official policy WHO keeps messing with the DRM settings every few months?

Please change them back again.
