I usually hook up differently.
STB(cable box) > TV > receiver.
DVD > TV
Your receiver has the DVD built in, so you just need to send video to the TV via HDMI.
If you run audio to your receiver from the STB, and a separate video cable to the TV you will very likely have lip sync issues due to newer LED/LCD TV's buffering the video.
If your receiver only has analog audio in (red and white), then the whole process becomes even more complicated.
If it has digital audio in (co-ax (orange or black) or optical), it should be very easy. Just be sure of the input, and confirm the TV you get has that particular audio OUT put.
Good luck,

I have a Samsung Reciever with a built-in DVD player, a time warner HDTV cable box, and will be getting a new LCD or Plasma HDTV with at least two HDMI inputs. What is the best way to connect these three devices with the best sounding audio and best quality video? The receiver is a 5.1 system and the television will be at a minimum 720p quality. I have several of the necessary cables such as two HDMI cables, an optical cable, and the speaker wires. Any help would be greatly appreciated.
