Good to know, but I've never tried to screenshot with it, so didn't know that was an issue.
On a related note, I get a side button beside the subtitle that allows me to copy/paste them, but I don't see that button on your screenshot. I use this to copy off dialog that I want to research more later.
Oh, I had to delve into setting and customize things a bit, I now have that one click subtitle copy button too as well as two layers of translations, one by humans and the oher by machine. And the change can often be huge! This is very helpful indeed.
Yeah, one of the things I find most interesting is the translators, at least for chinese, often translate the native chinese idioms to ones that are more familiar to the reader than the native saying. It's very annoying to me because you lose a lot of "flavor" of the show when they do that. In the beginning, having the machine translation helped a lot for that.
It was also useful to get a better match to actual word order when a line of dialog was split across several subtitles. Nowadays I've improved to the point that I don't use the machine translation much anymore though. But there's a bunch of useful settings in that dialog, expecially related to when you're studying characters vs pinyin in mandarin.
I also sometimes use it to slow down the speed at which people talk on shows when I'm listening to them. For example, slowing down speed to .875 or even .75 is tolerable.
