hi friends of rw web design,
a curious thing is happening to me. i just bought the “html 5” stack from @joeworkman and installed on the site of my client. it works great in preview, it works great in safari (my default browser when exporting the works to my upload folder \) but once the site is exported it says “error loading resource”. here’s the adress:

thanks much for any help i can get, tomas

Hi Tomas @tnittner
Works for me in Safari, Chrome and Opera, not so much in latest version of Firefox though
Resource link is good, video is in the proper location… not sure what the issue is with Firefox…
Maybe report to Joe?

@tnittner
Please see my PM about the wisdom of posting links to entire RW sandwiches publicly.

Hi Tomas,
Looks like your video file is corrupted, according to Firefox. When in doubt, always check your video URL in the browser it does not work in. As you can see on my screenshot, Firefox says it is corrupt.
How did you make the MP4? We always suggest you run it through [MiroVideo Converter](http://mirovideoconverter.com). It is free and has always worked for us.
