Hello friends

We have only tried playing the video on-line by just playing the MP4 files itself in various browsers.

We have NOT even gotten to using any video player like JW player or FlowPlayer, since the MP4 file on its own is already out of whack.

May the audio/video sync issues and the lag in IE go away simply by playing the same MP4 file in a Video Player?
(I figured if the source file is not playing correctly, there is no point in going even further and putting it into a Video Player... Wrong assumption?)

Have a good day.
