--- Comment #58 from Duncan Palmer <dpalmer at digisoft.tv> ---
I've just noticed that ccff3be3 removed the bitrate averaging added in
c98348c1. I don't think this is correct; queue2 keeps a moving bitrate average,
but only over a period of about 3 seconds. We sample this after downloading
each fragment.

The current solution will be as reactive to an increase in bitrate as it is to
a decrease, whereas c98348c1 was trying to make it reactive to a decreasing
bitrate but act more conservatively to an increasing bitrate.

I've proposed some changes to improve this in
