I tried making these changes but I'm still not able to view video or listen to audio. When I attempt to watch a TV show (recorded on Media Center) on my 770 through Orb I get a video_core.dll error on the media center pc. When I attempt to watch a video file or listen to an audio file on the 770 through Orb I get a "connection lost" message after a few seconds on the 770. Orb works fine on other pc's. I appreciate the suggestions so far but it looks like I need more help.

Edit: I just figured out my streaming audio and video problem. I didn't have RealPlayer installed on my pc for Orb to be able to convert the files for streaming. I'm disappointed in the video quality. Audio is fine. I'm still getting the error when I try to watch my Media Center recorded shows though.
