I know this original message was posted nearly 6 months ago but i thought i'd give you a bit of info. I too have a Sony Vaio, i bought it nearly 18 months ago and it came with a Blu-Ray reader and writer drive and WinDVD BD for Vaio pre-installed. Only now i can't play rental BD because i need to update the AACS and surprise, surprise i have to pay for it. Now i'm wondering how long it'll be before the player stops completely. As it's an OEM copy i'm not entitled to any support either, so just watch out, what at first seems really good, ends up just being as cak as everything else!
