dvd/vhs combo, HTDDW660 home theatre, cable box and Tv. To make it plain i have my system hooked up and working with the exception of sound from my t.v to my reciever. its an old t.v and it has 3 RCA's R,Wh,Y (line 1). the cable box has the same. The cable from the wall enters the cable box then out to the dvd/vhs combo then to the Tv. The only things left to play with are the 3 RCA's R,Wh,Y,(line in) on the dvd/vhs combo and the component RCA's R,BLU,GR on the dvd/vhs combo.And the RCA's of the t.v and cable box. hope this helps.
