laptop idea seems ok but overall it seems like the problem is your friends are dicks rather than anything with the technology
still, there are all kinds of solutions. check some of
$1 out
you could go hdmi splitter + hdmi to bluetooth adapter. put one wireless earbud in, you've got clear audio in one ear with volume you can control, and "RUN YOU STUPID HOE!" yelled at the tv in the other
you can also get some
$1 which are a bit pricey but now you're enjoying the film in sweet, sweet 7.1 dolby surround whilst all your friends are watching it in 2.1 audio like chumps. i have these. they're great for movies, games and music.
be warned, though. if you get the noise cancelling ones you can't hear *anything* outside, so if you're blind you'll be hellen keller'd in a world of music. im kinda paranoid about wearing them when im home alone cause someone could be robbing the house and i wouldnt hear anything
super cheap solution:
$1 back in the day, before bluetooth headphones we used these to listen to music from the same phone. this (get one that lets you control the volume) + 3 metre extender + any headphones you want and youve got a solution for like $15
i mention all these things cause youll continue to encounter situations like this as you get older, like when you go off to university and meet a bunch of new people. it's good to show up with the tools you need. a blind girl on a "crew" i was part of had a big tv, she her place was the place to watch movies. we'd gather there, put on a film, have some popcorn, narrate what was going on on screen, it was a good time.
$1 is how you change subtitle size in vlc. for most pirate releases they should load automatically. if not, you just take the subtitle file from the folder and drag it onto the video window, thats it. there's a motivation for your sighted friends to use it -- bunch of good features. most notably you can turn volume up to 200%, and roll volume up and down with your mouse scroll wheel. for movies that have annoying swings in volume between action and dialogue (action, thriller, etc.) we have a "mouse jockey" who keeps his or her finger on the wheel to maintain an appropriate level of sound lol
