The easiest way for me to do this is to take my laptop and connect a VGA cable to the TV PC vga input and the headphone audio out to the TV PC audio input and select the PC source on the TV. Then I can watch anything that can be accessed on the computer, including web videos like youtube, network tv shows, live webcasts, etc. To use this method you need a TV that has "PC input" in the sales jargon.
