Does a Yamaha htr 5830 have HD?

I'm not sure what you mean by "HD," but I've owned this receiver for almost two years and here's what it does have

- two Optical and one coax digital audio inputs

- two component video inputs and one component video output

these two features can be classified as HD as component video is rated just about the same as HDMI. The three digital audio inputs can be classifed as HD as well. Just remember that if you want HD quality from either a Set Top Box or a DVD player, you will need one cable for each of the video and audio. There are no HDMI inputs for this receiver. The nice thing about HDMI is that you can get both HD quality audio and video from one cable.

I hope this helps
