Cable Box Reverts to Set Up Every Time I Use It

Every time I try to use my cable box it goes to the set up screen asking my langauge preference. The remote doesn't work so I can't navigate. I have to unplig the box, reset the system, and wait for it to come online to be able to watch TV. Once reset the remote works fine as well.  I have had this subscription for about a year, so I am not a new customer tryign to set up my system.

Also, when I watch recorded shows, particulary sports, I often experience screen lag or it just locks up all together.
