Sorry to hear you had so much trouble.
A simple way to "stream video" is to "share" your drive; mount the shared drive on the other computers; and have them access the video files (or copy them locally to theirs) as if they were "local" to their computers, just use your shared drive as a "remote" drive.
Also, you once again have several identical computers. When you have problems, use my previous advice to your advantage and swap in known good parts to troubleshoot.
I'd also get something like Norton Ghost (lots of others), and get an external USB drive, and make a backup "image" of a computer (after loading all your software).
So...when (not if) one of the computers crashes, and since they are all the same, you can just restore the image to the computer (or the new HD for the crashed computer) and have all the drivers/software etc. load with the O/S in "one swoop". This won't restore any data/pics etc., but the computer will be back to its old self pretty easily.
Otherwise, you will have to go through the whole "load o/s, configure o/s, load latest device drivers, load ms office, load firefox, etc." process each time.
With the "image " method, you just load the whole thing at once, and change the computer name.
Remember, you have "friends" here that can help you....don't try to do it all by yourself![]()
