h264 plays in firefox but not in ie9 (does in ie8)
I encoded a video twice both in h264 using handbrake. one is 360p the other 720p. Both work fine in flash mode (ff and ie8) but not in html5 in ie9. (does seem to work on ios!).
The video can be seen here www.babybeth.net
I have looked in the documentation and it says the most common cause of this error is encoding in something other than h264 but I have done!!
