I encountered the same problem. In the end, I gave up uploading the video from the Roxio program and just did it directly on the Youtube site. To do this, I saved the video as a WMV file first. Not a big issue, but it is annoying.
Just got my capture card and enjoying it.
Was wondering if the editing tools allow for the insertion of arrows or other objects onto a video capture? I can do text, but arrows would be useful for some explanations I was planning to do.
