Czarek, if your DVD player has an HDMI input, you can indeed connect it to your TV via HDMI. If not, you will most likely need to utilize an RCA to HDMI Converter. The TU7000 includes a preinstalled Internet app; depending on what content you are viewing from the Internet, some content may not be compatible such as Adobe Flash Player. You can, however, take advantage of your TV's built-in App Store where you can choose and download from hundreds of apps, or you can Screen Mirror from your mobile device to your TV. ^Gina
