Need a little help with posted videos.

For some reason I can not view videos in a post. All I get is a black screen. If the address is posted I can click on the link and it is fine. Is it possible that a setting in internet explorer got changed ? I used to be able to view the videos just fine.

Thanks for the help.

My first suggestion would be not to use Internet Explorer.

If that's not a possibility review your Compatibility View settings. Tthey are usually under
- The tools menu (a little cogwheel)
or
- A "broken file" icon next to the URL
