The TV has 1 each of component video, s-video, hdmi, and analog audio inputs. Your options are limited if you want to use the TV speakers.
- For the DVR, you can just use the RF cable from the cable company as it carries both the audio and video. Coax from the wall to the DVR and from the DVR to the 'antenna in' of the TV. Alternatively, you could use HDMI directly from the DVR to the TV.
- For the other devices, you have only one way to get audio to the TV and that is through the 1 analog audio input, so you would have to choose just one device. If you choose a DVD player, you can use component video or s-video for the video and the analog audio. Now all of your connections are used up.
- If you get a receiver and speakers, you can use a single component video connection from the receiver's component video out to the TV and connect all of the devices to the receiver. The audio would go to the receiver. If you want DD/DTS capability, you must choose the receiver route because you need a digital connection and the TV does not have any digital inputs.
