In My Mediasite go to the presentation's summary page and click Record to launch the Mediasite Desktop Recorder. On the Mediasite Desktop Recorder Home (Recording Options) page, choose Upload Existing.
Click Upload next to the recorded presentation you want to upload to your Private folder.
Once you've selected the recording to upload, an upload status bar appears to show you the progress. Once the recording is uploaded to the Mediasite Server and processed, the presentation's status is updated to Recorded. You can now select Open Presentation to view the presentation if you wish.
