There is an option to add any other connected sites that you would like to use to the system if you would like to add, you will probably ahve to update as well.
In my experience yes. I have a SAT drive that I connect to it to play music, videos, and pictures. Remember if your CD's, or what your using is scratched up it may not play or if it has been previous damaged it may not work.
The answers given are partly right and partly wrong regarding the question. However there is wifi HDMI that eliminates a direct connect and having your DVD player next to your TV. It has a sender box that connects to your DVD player via a short HDMI cable (recommend v1.4 HDMI cables). The receiver end (located next to or behind your tv) is of course connected to your tv via another short HDMI cable. Now if you have more HDMI needs than your tv has; you can simply add what is called a Switcher, (which is different than a splitter: https://sewelldirect.com/articles/switches-vs-splitters.aspx ). Switchers can have 3, 4 or 5 HDMI inputs that allow you to connect to a tv that has only one HDMI input. Most switchers also have a hand remote to switch between devices (ROKU, apple TV, DVD, Playstation).
This needs to be connected to your router via ethernet cable and needs to be connected to your tv via hdmi cable or equivalent. This product does not have wireless capabilities, to the router nor to the tv.
Negatory. It has only one way to connect the video, and that is with HDMI. You do have the choice of routing the audio via either the HDMI cable or a separate coaxial cable.
I doubt that best buy/ geek squad will come out to install your new blu-Ray player but they are amazingly simply to hook up and use. You will need to purchase an HDMI cable (typically you can find one for about $10-$15) separately. After that you just need to plug the player into the outlet and connect the player to the tv via the HDMI and off you go.
I also have an older HD TV. My TV does not have HDMI inputs, but does have a DVI input. I used an HDMI to DVI converter dongle. This converted my TV's DVI input to HDMI, allowing me to use any HDMI cable. There are also cables available that are HDMI on one end and DVI on the other. The down side is DVI does not support sound, so you will have to connect audio through red/white RCA cable or optical cable.
