I can't make it yet work with mp4 files (hmmm iphone)
Argh! So stupid! There is the mp4 module for that!
Hmm it seems the module is made for Flashplayer.
Anyway I tested youtube's html5 feature (h264 videos) and we cannot
scrub the timeline outside of the downloaded zone, so I guess it's a
limitation of Quicktime 7.6.6. Maybe it works with QuicktimeX and
iphones, but as I don't have anything to test I can't confirm.
