We have an iPad1 running 4.3.2. I'd like to hook the iPad up to the TV so we can watch video from various TV apps like the ABC and NBC apps. Will this work? I've seen some vids on youtube, but they indicate that if you hook your iPad up to the TV via cables, you can only play youtube vids or movies you have on the iPad. Is that the case? If so, would I be able to play TV apps and stream via apple TV?
