Food Network fans will find several good channels in the food category on Roku. One of your first stops should be Chow, which offers close to a dozen series, with individual videos ranging in length from less than a minute to 15 minutes or more. Most are around two to five minutes, though, so don't expect half- to full-hour episodes like you get on the Food Network.
