Internet 10 error: unsupported video type or invalid file path

I created a website using Hype where I link to pages with videos. On Internet Explorer 10 for Windows, I get an Error: unsupported video type or file path. I confirmed that the mp4 videos work in Internet Explorer so it is not a video issue but maybe a file path issue or whatever. Anyone else see this problem?

You only mention IE, does the file work in other browser when played through the site?

Also it will be hard for anyone to help you as you have not given much details about how you have put the site together or indeed linked the videos.
Can you post some more details and if possible an example project that exhibits the same issue.
