I am about to demo the denon 2910 and 1910 on home trial. Can somebody please explain the effect that MB has on the image. What would be good demo material (film, chapter etc) if you have done this before. If I can see a difference in quality between the players I will go for the 2910, for better music caperbility and prog scan options. Unless there are other players worth considering at this price point, dont want to go over £500 but want HDMI/DVI to test with the VR5. Any help appreciated.
