- Having the special video card on your computer that allows you to watch regular TV on your computer. These may have an option to save the video as files which you can edit accordingly.
- Have a DVD recorder. Record your TV show as you would with a video tape... then, you'll need to convert the DVD video files to a format that you can update with software... you may be able to find software that will allow you to edit the DVD video files directly without conversion.
