Trying to mirror hulu from iPad to tv via hdmi adaptor. I get audio but no video

Have you tried unpluging and repluging the digital AV adapter with the HDMI connector plugged in?

Also, have you tried a hard reset of your iPad by holding down both the Home and sleep/wake buttons simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons?
