It could have been either. Most likely the player. The Samsungs just seem to really be fickle. I bought a BD-UP5000 based on the reviews and hype thiniking it would be the end all player...NOT. With it being a duo player, an ehternet port, profile 1.1 (via firmware update soon), promises of all the lossless audio and everything, how could you go wrong?
Well, you could, because it won't play half the time. Just look at the threads on AVS for all the details. LFoDH is one that half the players would play out of the box and half would not. Most of them do now, after the update released this week, but some still do not. I got mine to play out of the box, but had to go through hoops to get it to play. You may have to do the same with your 1400. If it didn't play, some had luck with ejecting the disc and reinserting it. Some had to eject, power off, power back on and reinsert the disc. There was just no rhyme or reason to the madness, just keep working with it and somehow, sometimes it would start playing
Iv'e had better luck with my 5000 than most, but it has trouble hooking up via HDMI and still won't play Mr. Woodcock on BD, no matter what, even after the update. My suggestion is if you want to try it again, to try powering off and back on a couple of times removing the disc each time and or ejecting and reinserting the disc to see if it will play. If not, you could try another disc as you could have gotten a bad one (although I know you will have to go to another store

).
As for my 5000, if they don't come out with another firmware update to take care of these playability problems by the end of the month (my return window) it's going back. They promise an update to fix the lack of bitstreaming the lossless audio...in May


but I don't know. The current update did fix it where I could watch 3:10 to Yuma though. Yay.

I'm bitter as I really wanted to love this player. I just can't right now.
