You may find a DVD changer or something that will connect to the Internet to obtain disc info or something like that, but if you have information on your computer that you want to get to your TV, you should look for a network video adapter. A DVD player is built for playing DVDs first and foremost, so odds are strong that no manufacturer will make one that so specifically connects to a network.
On the other hand, you can find networkable video players & adapters to connect your PC to your TVs in your home very easily. I haven't used any but have read a little about them. I'm sure you will hear better responses from others who have at least used or done more research on network video players.
