Incidentally I bought my first Blu-Ray player yesterday. Quite a contrast to when DVD was the latest technology because I bought a DVD player very quickly. I remember asking at the video rental where they had DVDs and the girl behind the counter responded with a confused expression on her face and "Where is _what_ ??"
Don't expect to buy that many Blu-Rays but I wanted to be able to route my DVDs through HDMI to my receiver and then to my TV instead of SCART to TV and coax audio to receiver.
I paid an insane price for that SCART cable by the way, but it was worth it for all those years (it looks more like a chain to secure your bike

).
I also have a great sounding surround audio set-up but there is always something very special about watching a movie in a real theatre.
