I'm in the UK and have a Sony BDP-S300 Blu-ray disc player. I've just bought a high definition camcorder and will want to create Blu-ray discs of my HD projects. But I've been told that "home-made" Blu-ray discs won't play on my Sony Blu-ray players unless the player is modified by using some kind of unlocking code via the remote control. Can anybody please advise me on this? Many thanks.
