mp4 streaming/seeking works from firefox (fedora) and not from firefox (windows) (nginx 1.9.3)

[tunist]

i thought i had solved this by adding the header for accept-ranges - since
when i did that i could then seek in firefox on windows 7. however, after
testing further i found that the results are inconsistent and ultimately it
is still somewhat broken.
i have added more details to this to a new question i have asked at
serverfault:
http://serverfault.com/questions/710304/why-is-partial-content-not-being-served-in-nginx-mp4

any input is still welcome!
