You can stream it from YouTube or livestream. If you have an iPhone or iPad you can AirPlay to your tv from your device. This is how I watch the podcasts.
I use a PC, but here is what I do to stream the live shows to my 55" TV.
I play it on the computer from Livestream (usually the saved one and not live since I live in Alaska). I have a videocard that allows me to have a computer monitor and HDMI output stream at the same time, so I have the video/audio sent out via the HDMI port on my video card the 50ft to my TV...lol. Much to my suprise it carries the sound as well - I just have to remember to set my sound to play to the "TV" device.
I'm running a NVIDIA GeForce GTX 580 1.5GB 16X PCIe Video Card if that helps.
It works great and I have the sound go with it. It's pretty fun to watch with my DW while kicked back on recline...
