Alien Anthology and Samsung BD-P2500 (Others too) F/W Update????

[Sammy]

On amazon's product page for Alien Anthology there is a note about updating firmware for the Samsung BD-P2550 (2500) and other players that people on here may have:

Please note: The following Blu-ray players might need a firmware update to ensure successful playback of this product: Panasonic BD10 and BD80; PS3; Sharp HDS43, BD-HP21, and BD-HP20; Sony BDP-N460, 370, and 350; Samsung 1000, 1200, 1590, 2550, and BD-P3600; Oppo BD80 and BD83.

My question is specific to my player. I checked the firmware on the player through the internet connection and it says it is the latest firmware but the file number for the download from Samsung's website shows it is more recent (November '09 vs April '10) Previously I have not had to use the USB flashdrive method to upgrade my firmware but have always updated vie the internet / ethernet connection on the player.

Has anybody else run across this issue?

Does anybody know what the update is for on this specific title?
