Have you updated the firmware on it? I had a similar problem with a Sony blu-ray player and I had to download an update and burn it on to a CD then allow the CD to update the blu-ray player. What's the model number of your player, I may be able to get a link to the update for you.

To set DVD Region to “0”, download file “6000.zip” (often also called “LG6000.zip”) from here:

http://www.multi-region.net/_media/6000.zip

Save the file and then unzip and extract it to your hard drive.

Now burn the subdirectory RMTM0000 and its contents (not the text file) onto a CD-ROM (ISO format, “closed” CD-ROM).

Insert CD-ROM into the LG BD 370 P player, and when the Region Management System screen is displayed, set the Region Code to “0” using your remote. Once done, press “PAUSE” on you remote to save, and you’re done!

From the Samsung manual: "For further information on Pandora service or to unsubscribe the Pandora service, email samsungsupport@
pandora.com."

Probably need to include the email address that you want to unsubscribe/deactivate on the Samsung Blu-ray player.

The photo you put suggests a Samsung BD-P1500 Blu-Ray player which doesn't appear to have Netflix Streaming built in to the player. Follow this link for Samsung players that do support Netflix:
