Streaming video is latency sensitive and RC4 is the least intensive algorithm. The volume of information in a video stream makes RC4 difficult to crack unless the payload is high value and target specific, which your Netflix streams are not.
Actually, *difficult* is probably the wrong word, but one would optimally need to capture the entire stream to ensure whole frames are captured, at least between I-frames.
The wording of this question is ambiguous and implies a scenario such as a Netflix stream which is bandwidth intensive and latency sensitive. I sensitive video teleconference which needs a level of non-repudiation would need a better cipher.
