Help please. Ps3 and Pioneer VSX-9040TXH

Was very excited to get my new Pioneer VSX-9040txh. Set it up with my Rogers HD box going through HDMI input 1 and working perfectly in HD on my Sharp Aquos TV. I ended up plugging my ps3 into the BD HDMI input thinking this should work as well. However, when I go to the BD input on the receiver my TV is showing that the PS3 is only outputting at 480p. I tried looking at my PS3 settings but they seem to be right. I tried to change the input on the receiver from BD to HDMI2 but the results were the same. I then tried to see if I followed the instructions on pg 68 on changing the Video Paramaters on the receiver but when I click the Video Paramater button it says that the function is not available. My PS3 was playing in HD when I run it directly through the TV. Was looking forward to watching my Iron Man BD disk with the beauty sound from the receiver but want it, obviously, in HD. What am I doing wrong. Any help would be greatly appreciated.
