Anybody got any thoughts?

Does the studfinder work properly on other walls? If not, try a different studfinder. If so, I got nothin'.

Studfinders work very poorly on plaster walls. Something about how the plaster is put up.

I hate my plaster walls.

Oh! I meant to add, the one thing that has worked (with about a 50% success rate) for me to find a stud in plaster is the magnet-on-a-string method. Suspend a strong magnet from a string and hold it so the magnet is about a 1/2 cm from the wall. Move it up and down and side to side very slowly. If the magnet gets pulled into the wall, then you are over a nail - the nails that hold the lath onto the stud! You should be able to lift the magnet up and down on the same vertical line and find more nails. Attach a screw anywhere on that vertical and you should be good. If you can find two in a row and measure the distance, then you have a reasonable guess for how far apart the studs are and can mark them all the way across and pray.

If you use a very strong magnet, (I use a little rod made of 5-6 strong rare earth magnets), then you can move pretty quickly; even the magnetic pull from a nail 2 inches under plaster will pull a strong magnet solidly into the wall.

I come across enough shows on Hulu Plus that have the "oh so sad we can only stream this on a computer not a device" flag that I'm pretty devoted to the Mac Mini we have plugged into the TV. It's not a cheap option, but it works for everything.

Yeah, I used to be a big HTPC fan for that reason. And that would clearly work for HBO Go too. But every time I've had an HTPC (usually old Macbooks that I ended up selling eventually), I ran into interface issues - I just don't really like controlling TV from a mouse/keyboard if I can help it, and the media desktop apps all seem to be missing features; Plex Desktop is great for local media, and works fine from a remote, but you couldn't really do Netflix on it so I'd have to open the website and go all mouse/keyboard. XBMC is similar.

I plug my computer into the TV if I must, and control it using the Universal Remote mobile app, but for $45 a Roku can't be beat for the things it can do, which is almost everything streaming (and even a lot of local DLNA playback - my old Roku 2 XS handles 1080p MKVs served by my router just fine, and Plex works great on it too). Since the Chromecast can actually cast Chrome tabs wirelessly (and mirror some Android phones, though not my slightly older model), that covers a lot too; I haven't tested it with "no-device" Hulu shows yet, but I should...

Your router is serving media? What kind do you have?

Asus N113u I think? It's one of the high end Asus routers, but without AC support. Came recommended by LifeHacker. Comes with a DLNA server out of the box for attached external hard drives, and you can also easily add your own optware packages; I have a Transmission client as well for downloading torrents. Lots of other options as well.

I should check if dd-wrt does that--it might be what pushes me over to installing it on my router. If I could pick one thing on my network to serve consistently, I wouldn't have to worry about exceeding any given storage device's capacity and spread my library across them.

I swear to dog this wall doesn't have a single stud in it

If you can't find a stud, there's a more brute force option - [link] Those suckers will hold anything.

Hmm. I should check the shows I would be watching (Arrow, SHIELD, the Flash, possibly Gotham, possibly Constantine [oh Jesus, it's all comic book shows I AM SO PREDICTABLE]) and see if they have that flag. That would be annoying.
