Yes, I tried qt-faststart but it didn't help. I don't know AtomicParsley maybe I will give it a try. In your experience the default behaviour for an encoded mp4 file (-vcodec libx264) should allow seeking without downloading everything up to the seeking point?

Did you use qt-faststart or any other tool (AtomicParsley...) to relocate the meta to the beginning of the file...?
