Well, I'm looking for assistance? I have the add on and all the software updates. My 360 is connected to my Denon HD receiver and then to my Aquos 52" 1080p monitor. Anytime that I change in the setup to 1080p the screen goes blank for a few seconds and then comes back 1080i. I'm guessing that I'm not seeing the video that would allow me to retain the setting, so I feel that I'm not getting 1080p. Does anyone else have this issue? I could attempt to hook straight up to TV, but its not that important to me. Seeing I would never keep that hook up, I have a wall mount and don't feel like pulling another cable through the wall, not mentioning messing up my whole setup due to length of cable. If anyone knows how I can fix this without an additional cable pull, I would greatly appreciate it. By the way XBOX 360 support has no idea, not a clue, they acted like I was speaking french. Appreciate your comments.
