I have a PS3 (for a while anyways) and a Toshiba A2 HD-DVD player.
I rented Batman Begins in BD so I could compare it to the HD version I already owned. I could not tell the difference between the two.
I borrowed the Satellite Dish HDMI connection on my receiver to hook em both up at the same time and flip back and forth using the remote. I couldn't really sync them up and switching took a few seconds for it to go back and forth so it's not overly scientific but If I couldn't tell the difference at this level, I'm certainly not concerned with what I might have missed.
