Question about flicker and 100hz

[ijustblumyself]

Okay so a quick question, is it normal when watching movies/TV shows for the noise of the transfer to almost.. flicker on the screen for some blu-rays?

For example I was watching some of season 6 of Mad Men and the noise in some scenes was making the screen flicker to a degree where I was distracted. I'm not sure if this may be due to the fact that I'm outputting at 24hz on a 100hz TV, or if this is just a part of the blu-ray.

Any help is appreciated, thanks!
