What equipment do I need to connect my 2008 Mac Book to my LG HDTV to stream tv shows from Netflix?

Do you have the 13" white plastic or aluminum unibody MacBook or the 15" aluminum MacBook Pro?

You've got the Early 2008 model 4,1 with the Mini-DVI port.

Depends on what input plug you'll be using on your TV. VGA, DVI, Composite or HDMI. You'll need a Mini-DVI adapter and a cable from that to your TV. Here's the various types of Mini-DVI adapters on Amazon.com http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=min i-dvi&x=9&y=13

(Composite is the red, white and yellow RCA plugs on your TV or red, white and S-Video plugs.)

If you use VGA, DVI or Composite you'll also need audio cables to the TV using a 3.5mm stereo headphone jack to RCA sound plugs or a 3.5mm stereo input plug for audio. You attach it from the headphone jack of your MacBook to the appropriate audio input plugs on your TV.

If you connect the MacBook using a Mini-DVI to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo system for audio if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug. You attach it from the headphone jack of your MacBook to the appropriate audio input plugs.

The Mini-DVI to HDMI doesn't carry audio and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI. Check your TV manual though to see if it might have audio plugs that work with one of the HDMI ports.

Many TVs these days have built-in Netflix. Double check if there is an ethernet port. If it is, connect it to your router. Then configure based on the manufacturer's setup for Netflix.
