Yep - I second Gonk's recommendation. Finding a good universal player that excels in all areas is pretty much impossible. Find a good DVD-A/SACD player (you already have one and seem happy with it) and find a good DVD-Video player.

The Oppo certainly fits the bill of good DVD-Video and if you just get the Oppo you've definitely saved money over having to go to a higher end Denon Universal device to get your DVI and DVD-A/SACD.

Don't forget if you get the Oppo to check its firmware when you get it and update it to the latest if necessary. Makes a big difference.
