Two uploads issues

Hi!

I’m having a problem with video upload.

I’m using a social media theme named Klein that uses rtMedia for the media part. When I do an upload in the user page, it appears that the video is uploaded, and the video also appears also lists. But when I click to watch it, the video don’t run. It appears to be broken, just shows a black screen with some codes in the background. To see an example: click in a video in this page: http://videotecapopular.com/members/videotecapop/media/video/

In this project, my client wants to have an host service dedicated only to the store the videos. Is there a way to configure rtMedia make the uploads in another server?
