Splitting - DirecTV DVR

For DirecTV TV services which include DVRs and receivers, Splitting I want to split from one tv to another so I can watch the same thing on two tvs. I have the Jenny system on 4 tvs in my house but I want to add another tv in my living room and watch the same Chanel on two tvs. Can I use a regular splitter or do I have to have a special splitter ?
