Any help why its not playing in simulator.

Thanks in advance.

I have seen this before when there are url issues -- like capitalization... The simulator is more relaxed than the device... Check the exact file names...

Sounds like it might be a pathing issue. You are using relative pathnames for the video, so they need to be in the place the HTML expects them to be in order to find them. You'll need to either use absolute pathnames to the files in your bundle OR make sure that the base href is defined to point to the appropriate folder holding those images, either explicitly in the HTML or by specifying the correct baseref in the loadHTMLString:baseURL: call.

One way to quickly test whether this is a problem would be to put a .png next to the video files and reference it in the HTML, too. If the .png doesn't show up, it's not a video problem so much as a problem finding assets.

i read that the mp4 file should be placed before the ogv file for the iPad to play it.

I am playing an m4v file in my uiwebview, but the translucent 'play' button does not appear in my simulator. It does work on the device itself, though....

        <video id="VideoDiv" preload src="http://www.movietime.com/movie.m4v" controls width="480px" height="270" poster="poster.png"></video>
