Good evening guys. I have a HR20 and a Sammy 46" DLP. The Direct TV installer had the remote working fine until I thought it would be a good idea to reboot the HR20. I've searched the forums and followed the on-screen instrux to no avail. The remote that came with the HR20 works the HR20 fine but if I need to turn the TV off it won't work and if I need to change the 'TV INPUT' to switch to DVD player that doesn't work either. I've entered the codes, followed the directions, anything I'm missing? However the volume does work.
