How do I connect my dvd/vcr player,dvr cable box,dvd recorder, and home theater system to my HD TV? - dvr dvd player

I have an RCA HDTV, digital SV 2000 DVD / VCR, Apex Digital Home Theater, Cable, Direct TV and a DVD burner Liteon. I could not login because I have them before. Year was told to buy a DVD recorder, to watch the movies he watched on cable since 2000, only became known as the SV record playing.Can me (the person completely non-technical) has been based in simple words, such as components and connect them?
