Odd Question That I Can't Classify

[beware]

I have 2 bluray players, Samsung BD1500 and 1600. They are relatively old and are not without glitches from time to time...

With all that being said, I got The Condemned on bluray this weekend, popped it into the 1600 and the player has a hard time reading the disc at the very beginning of the first trailer resulting in freezing or pixelating but it quickly fixing itself with all other previews and the film itself without glitch.

Now on the 1500, said glitch isn't there at all.

Had some free time and thought it was firmware, so upgraded but still glitch is there on 1600 but not 1500.

Like I said, it literally only happens while loading the beginning of the first trailer and it corrects itself never to have issue again.

Not a disc issue as it depends if glitch is there due to player.

What do you think? Should I worry? Never experienced said issue before and like I said only happens on the part of the disc I can't care any less for. Firmware didn't fix it, no scratches on the disc...

anyone know?
