As we described before there are several different ways you can play or video media file from a SharePoint 2010 site. There are prons and cons on each of the implementation. You could refer the blog for details.
When we utilize the our of box Content Query Web Part to display audio or video files on SharePoint 2010, we found one issue that is impacting the usability. The issue is when you have a Content Query Web Part on a page, it overlay and block any other system pages or configuration options. As a result, users could not configure the web part or could not perform other activities such as create list since those options are overlapped blocked by the black box of the Content Query Web Part. Here are some examples of the issue.
1. If you try to configure the Content Query Web Part, the menu is blocked by the web part and it's very difficult to identify the Configure Web part menu option. See the screen shot.
2. If you want to create other lists or pages from "Site Actions" -> "More Options", the whole Create page might be blocked by the Content Query Web Part.
Of cause, we could use different ways to play or video media file from a SharePoint 2010 site. However, some users just want to get this working to display YouTube videos as I setup even back in SharePoint 2007 version. At this time, I'm not able to resolve this issue.
Does anyone have similar issue and have any solution or workaround?
