DFW CBS O&Os are gone now. replaced with the dispute slate.
i guess one of the two parties involved walked out on negotiations in anger.
meanwhile, we DirecTV customers suffer from this.
there are options. get the LCC/AM21/hook up antenna for OTA signals, watch via locast app or locast site, sign up for CBS All Access and get the free trial or watch the shows vis CBS or CW's sites. also wait a few weeks before making that switch providers decision (unless you are already planning on it and found your camel's back breaking straw out of this.)
and also, you could try to send a message or call your local congressman or senator and the FCC about them trying to change the laws to where these retransmission disputes are stopped dead and make the locals be aired under must carry rules or make distance stations be able to broadcast in markers where a dispute is happening at.
