Connect Your Hard Disk to the TV
Take a look at your USB connectors on the TV. Some TVs may have more than one, and if so one of them might be labeled as USB/HDD. That's the one you want to use for your hard drive. If there's only one, or if none of them are labeled specifically for the hard drive, don't worry about it. Just use what you've got. When you plug the hard drive into the USB port, you should feel a slight vibration as it's recognized and read by the TV. Depending on the case it's in, you may also be able to see a light flickering on and off. Use your remote to choose the USB drive as your input device, and you should be able to see your content using the TV's built in file browser. Just choose the file you want to watch, and select it with the remote. It should begin playing.
Choosing Compatible Files
It's important to remember that your TV probably won't be able to recognize as many types of media files as your computer. Your user manual should tell you which file types your TV can recognize, or if you've lost your manual you can check the manufacturer's website. If all else fails, you can always try a clip and see if it works. If not, you'll have to convert the file into something your TV can recognize. If you have the free VLC Media Player on your computer, you can use that to convert between most audio and video file types. Bear in mind that if the file is protected by some form of digital rights management, or DRM, it's against U.S. law to break it for the sake of making a copy.
