Summary: I have had this player for about a year. The player is very very very slow in every respect, loading discs, powering up, setting options, upgrading firmware etc. The player is buggy it will crash, hang, and loose sync 25% of the time. So one out of every four times i use this player I have to wait over 10 minutes before I can watch the movie, and one out of every five blu-ray discs dont play at all or stop working part way through.
Summary: I had very high hopes for this machine when I purchased it from a local Denon dealer with cash I had been given as a gift. I have some SACD's and DVD audio discs, a huge collection of DVD's and CD's, and was ready to begin a collection of Blu-ray discs. I am running the player connected to a Denon AVR 4310CI receiver with which I am greatly pleased. When the player works, the sound and picture are outstanding. I have been tremendously disappointed from the onset.
Summary: I would've liked to report something good about the Denon A1UDCI and the folks here at Home Theater Store who sold it to me. Unfortunately, I can't. My flagship Denon has an audio issue. On some BD discs which play flawlessly in other blu-ray disc players, the soundtrack in this machine cuts off twice in the midst of a show until given a quick fast-forward or reverse nudge with a button on its remote. Then the audio comes back on.
