Video iPod to TV

I love social networking! Thanks to a pal on my twitter feed I learned of a $2.10 cable for connecting a video iPod to a tv (which, thanks to PTA, all of our classrooms possess). After hooking it up I was able to get audio but no video. A dear, sweet techy cousin found this link for me... and now it is working! So basically, I had to go to Video>Video settings>TV out and turn it on. BINGO! Thanks to all involved and now my third graders can experience the cool Schoolhouse Rock videos that I purchased from iTunes!
