you could use something like MythTV. http://www.mythtv.org/index.php
So i have had a desktop running Windows Vista Ultimate natively. I also have been using a built in TV turner and enjoy watching my Verizon Fios TV shows on it. It works perfectly fine as my DVR and Media Center. I recently bought a Windows Vista Ultimate laptop, but it doesn't have a TV turner. It has 3GB ram, and is quite fast. I want to be able to watch the TV shows that are playing live on the desktop on my new laptop. Is this possible? and if so, what do i need to do?
