fbs - Yes the DVD player is set to 480p/576p (NTSC/PAL unit).
There are two types of menu on the RX-V2500 - a fascia driven display activated by pressing "DISPLAY" on the remote, and the full GUI by selecting "TOP" (making sure the switch on the right hand side of the remote is set to AMP).
If youve tried everything and still no joy, can you bring it to the store you bought it from?
