That should have been I don't think limelight has ever served HD content.

Yes it would have come from Level3 if Akamai was excluded.

No what you are getting is not a good speed. I have just tried a 1 hour episode of Homes Under the Hammer in HD and got around 300fps and the download took about 6 minutes.

In the not too distant future, HLS will become the only option for us to use. The BBC are planning to get rid of the RTMP streams in the near future but we don't know when. The RTMP options could disappear at any time though.
