NOT TRUEDVI will do you little good even if your display has a DVI input because there is an additonal digital to analog conversion at the disply which can mess with the signal (certain plasma displays with DVI are the exception)
Not only will Digital DVI help PQ of LCD and some Plasmas; but don't forget about DLP and LCOS fixed pixel displays. I've seen this DVD player hooked up to a Samsung 46" DLP Display and it is absolutely stunning. With this set-up, the signal is never in analog format.
