Thanks guys. I wasn't using the guide. I was just punching in some local Chicago channels (2, 5, 7, 9, etc.) and they would default into 480i with the pop up 'Watch in HD? box. So, I guess this is normal if you don't bring up the guide and select the HD channel.
I'm so used to Directv bringing up every channel in HD, if I use the guide or just punch in the channel number on the remote.
I'll go over there tomorrow and use the guide.
