Internet reviews & searchs mention using parts of ready-made DVDs. In still photography there are freeware & commercial files to test projectors, cameras, etc. What commercial DVD extracts are best for alignment of HD TVs? Is it ok that I hire the DVD, then just use a section (30 seconds) for setting?
I'd like to have presets for day, night, Ektachrome dazzle or Kodachrome boring reality. Any other suggestion?
