WiFi vs powerline networking is very much house-specific. Modern WiFi works great in most places these days, but it matters what's in the walls between here and there. Powerline networking works great in some places, but other are wired so there there's no signal at all between certain rooms, because of deliberate isolation (only heard o fthat in newer houses). One or the other is pretty likely to work for you, if you can't get GbE wired where you need it. At least try to wire up your most-used TV.
I use the Handbrake command line to rip these days, because of the DVD/BR trickery, language choices, and so on. With a few scripts I get the audio and subtitle tracks I want, reliably. I have a little program to scan the DVD (using handbrake) and generate a ripping script, needing as input only whether it's an animated title, which 90% of the time I can just run. It's only the stupid BluRays where there are many bogus titles that it takes me more than a few seconds of effort these days.
BTW, Disney isn't the main villain when it comes to the fake BR tracks, that's LionsGate. I haven't seen that from Disney for some time now (Disney cartoons do typically have 1 title choice per language, since they localize on-screen writing and sometimes the credits, but that's just a few titles to sort out, not the 9-title puzzle box).
