Legally (and in terms of the x10Hosting terms of service) there shouldn't be a problem -- provided that the Camtasia videos don't involve instructions for cracking, warez or copyright violation. You may, however, run into problems with resource use. It would be far better to upload the video to something like YouTube and just put the video embed code on your page rather than trying to allow users to download from your page. (If you do want to allow downloads, well, videos tend to be big files and torrents are the only good way to ensure reliable downloads of big files. Unfortunately, it's hard to find a torrent tracker that doesn't also allow torrents of warez, keygens and pirated material. For that reason, torrents are verboten here -- one bad torrent can cause no end of trouble for x10Hosting, and your business isn't worth risking theirs.)
