Firstly, go to Start > All Programs > Accessories > System Tools and open the System Information tool. Expand the Components list, check your audio (sound) and video (display) card models and download and install the latest drivers from the developers web pages. After that, uninstall and reinstall Ulead VideoStudio and try again to record the videos. Once you finish the recording process go to YouTube Upload page, log in using your account and upload the files manually using the Upload button or the drag and drop feature. If you still have problems, I suggest you use Google search engine to find tutorials, guides and tips that will help you to record the Xbox videos and upload them to YouTube.
