Unfortunately, I don't have any information on the BD-P1580. Being in the U.S., I can only speak on U.S. products. I might suggest calling the customer service center in the UK, which can be reached at 0845-SAMSUNG. I wish I could help further, but I can't speak for products in regions outside of the U.S.
I recently bought a Samsung 1580 in the UK, and was hoping to use the youtube facility unfortunetly the youtube logo on the "a" (red button) does not appear on the switch on screen as described. I have updated the firmware to the latest version 2.05 hoping this would fix this issue
Please can you advise
