I picked up my 5000 at Best Buy in Salinas, CA yesterday. I was feeling pretty good, walk in asked if they had any in stock, the manager said they had one that just came in that day. I bought it with a 12 % discount coupon. I took it home and opened up the box and realized this unit was to be a floor model. It had a display sign in the box.
Hooked it up to my system, HDMI to my Sony XBR2, optical audio to my Onyko 803. Here is my very limited, non-technical review after watching one Blue Ray movie (Ratatouille), the first part of a HD DVD (Shooter) and the first part of a SD DVD (Bourne Ultimatium). Her goes:
The Good

1. Great Picture. Really takes advantage of the full 1080P of my XBR2
2. Great Audio. Much better then my Pioneer Ellite 47.
3. Great Upconversion. Bourne Ultimatium look great not HD but better then my Pioneer Ellite 47
Issues :

1. While watching the Blue Ray Disk (Ratatoulle) I noticed the camera angle icon consistentantly appearing for no apparent reason. When the icon appeared, there was a small clitch in the audio for a very brief moment. The icon would remain on screen from 30 seconds to over a minute. This would happen 10 or more times during the movie. I thought because I did not follow the instructions for setup, but rather hooked up the player and put in the disk, that was the cause of the problem. I went through the setup and setup the audio and all other settings as instructed. I replayed the disk again and the camera angle icon appeared again. I did not watch the entire movie again.
2. When starting a movie (Blue Ray Ratatoulle) during the downloading mode, the download graphic in the middle of the screen was clear but on each side oof the graphic there were some very wierd colors with pulsating bands. I should point out this only happen once. I had to re-sart the movie again to correct the problem.
3. While watching the Blue Ray disk, the remote control and the controls on the player consistently locked up and became inoperable. This usually happens when you attempt to stop the movie and try to re-start. One this happens you cannot stop the movie or use any of the controls on the remote except the power button. The only way to stop the movie is to power down the player. The instructions states that when this happens, remove the batteries from the remote and hold down on one or two buttons for 1-2 minutes to discharge the micro-processors in the remote. It seems to work.
I should note. that these problems don't seem to happen when watching a HD DVD. Although, I have only watched 2-5 minutes of the HD DVD, the remote seemed to work fine and the camera angle icon did not appear. I was not able to stop the player and resume where I left off. I don't know if this was because of the particular scene of the movie or the disk, as the instruction manual states, or if this is a problem with the player or the remote.
I will be watching the entire HD DVD (Shooter) tonight and be watching very closely for any of the issues I noticed while watching the Blue Ray Disk (Ratatoule).
I really think these issues can be corrected with a software up date. I will be calling Samsung tomorrow and talk to their technical service people and see what they have to say.
I have a question for everyone out there. If these problems are resolved, and I decide to keep the 5000, would you purchase the 4-year extended warranty from Best Buy for $79.00? I think I would to prevent future problems and also the possiblity of 2-3 years from now exchanging the player for the replacement model if the unit cannot be repaired.
I was so excited yesterday to score one of these players and I am still optimistic that the issues can be resolved.
I will post an update after I have had chance ot use the player more.
I am sorry for the non-technical review, but this is my first take after using the Samsung BD-UP5000 for a little less then 24 hours.
