mp4 videos converted from Video converter Pro 5 doesn't work in Google Chrome

[EcuaDrive]

Hi all. I'm a webdesigner and depended on that videos (mp4) works in all web browsers. But as is now they don't work in Google chrome, but seams working in all other browsers ??
Very strange, or are there specific settings you have to perform? As it is now I have to workarround with a Free Video converter that fixes this issue.
Hope someone has a good answer

Hi, I already recommended an alternative for video converting in another topic, hope that will help.
Moreover, make sure it's not Chrome's fault.
