What a question – like as if there was an “easy” answer out there. I’m sure there are whole books written on this topic, and I’m not going to write one here, but I will make some comments.
There is no “silver bullet” to accomplish all of what you want to do – especially by this weekend! But, over time, you could get pretty close to what you want to accomplish.
First, it helps to have a top notch router to run the whole show, as well as wired (not all wireless) connections throughout the house, and all running at gigabit speed. And, if any of your media will be from internet sources, you also need to have high bandwidth from your internet provider (30mbps at least) to match what the home network can dish out and handle coming in from outside. High quality internet requires a high quality DOCSIS 3 modem. Basically, it’s a horsepower kind of thing throughout the entire home network.
You could have a WDTV for each TV, and yes, you can run more than one movie at a time (to different devices, e.g… TVs, computers, mobile devices etc) if you have the above requirements or close to them.
My network includes the above requirements, and for a “stress test” I have had about five streams, e.g.music, movies from drives, movies from Netflix, etc, going through the router at once, and most of it from one WDTV, playing on the TV with WD attached to it, and going to another TV with a WD attached to it, a couple of computers, an iPad, etc. .
And, it all works, although most people don’t use their system like this; they play something here and/or there, but not everywhere at once.
As for playing on mobile devices, that’s a whole 'nother discussion, but suffice to say that by using certain iPad apps, I can stream music, mp4 files and even 1080p movie files to my iPad. Some 1080p files stream this way, but not all of them. I likely need a more robust computer. (next purchase!)
Do you get the feeling I am talking money, money, and more money. I am, and to spend it all at once is a lot of it for most people. So, like most people’s, my system has taken a few years of purchasing things every so often to get to the point where it can today, do the sorts of things you’ve mentioned.
It also takes getting educated about all this stuff, and then making informed decisions of what to buy. So, use patience to get things learned and done (and not by this weekend!)
One last comment about this one of yours: “None of my TV’s are internet ready(dlna).”
It appears to me you are equating “internet ready” and “DLNA” as being the same or closely related, and they are not. Neither of my TVs are the newer “Smart TVs” that are DLNA-enabled, although one is “internet ready” in that it can snag streaming content to play and get firmware downloads.
My suggestion to you is take things a little slower, get ONE upgrade done before you tackle the next, and do it all in a logical order. Most of all, have fun doing it.
