I picked this unit up two weeks ago. It was a March 2008 build and after I did a firmware update I got no video, and the USB port was not functional.
Brought it back to the store for an exchange, picked up a new in box one which was a Feb 2008 build and guess what! I got this problem right out of the box!
I got this unit so I could use my A20 as a backup, but so far I'm 0/2. It goes back for a full refund tomorrow.
EDIT*** 0/3 NOW! Since I bought the last one at my BBY last night, I drove to another BBY to pick up another one! This was a March 2008 build and it had the same problem as my last one. All I get is "PLEASE WAIT" I'm so frustrated right now. I would love it if this player worked but I'm really ticked off right now.
