Streaming abroad, what is prohibited?

I have a bunch of channels with TWC/Spectrum and HBO/Showtime/Epix/ and a couple more movie channels.
So I'll be in Vienna for a month and was wondering if I will be able to stream my regular network shows and some movies I have on my Roamio now. I thought I've read somewhere that some shows, or "networks" were protected and couldn't be stream out of home (or out of country)? Seems to be a lot of info on this out there but mostly outdated and conflicting.
Anyone do this outside of the US?...
