One danger is that videos can now "phone home" with the TV they're viewed on. You could torrent through Tor and take all sorts of precautions, then watch on your TV at home and leak your viewing habits. Or worse, get someone else targeted for copyright enforcement if you watch pirated content on their TV.

How would data in the video be used to direct the TV to phone home? As in, what field would be set?

I guess it would be a watermark style change through all the video frames which affects the hashes - e.g. brightness or contrast or sharpness or some combination of that kind of thing - then seed that on torrent sites, and advertisers get to see which TVs watched the torrented film vs the official film.
