During testing, it appeared that Hulu won't allow seeking or pausing(UI would become unresponsive) when HTMLMediaElement.readyState < HAVE_ENOUGH_DATA. 

The observed behavior is that the app appends one 5s segment(two actually, one audio and one video) every 5 seconds, but the UA keeps switching the readyState between HAVE_ENOUGH and HAVE_FUTURE, which, correct me if I am wrong, I believe shouldn't happen.
