Playing a video from the local filesystem has the same effect. Networking is not the issue since video playback works perfectly fine in WebKit-based browsers.

For example, compare the playback of https://www.youtube.com/watch?v=K0Tsa3smr1w on Firefox at 3.5 speed v the same on Safari: audio on Safari is much smoother than FF, especially since FF skips audio every few seconds. Human speech is practically undescipherable on FF, but is smooth on Safari.
