I'm looking to upgrade my dvd player. Is the denon 5910 still the one to have. Are there any other units that I should consider in this $$ range.

How does the Marantz dv 9600 compare to the Denon?

In all honesty, the 3930 gives you 95% of the performance of the 5910 at 50% of the price. Take a look at the 3930 Secret's review.
