I've noticed that many movies/TV shows get released on Blu-Ray, or are shown on HD channels, that were not filmed on HD cameras. How can they make a HD version when the source was not HD? This especially applies to silent films. Isn't true HD always at a resolution that fills up the screen, instead of SD, which has bars on the side and/or top and bottom? I think my question shows that I am not fully educated on the subject.
