I see this used to come with a "free" blu ray - but now it doesn't. Still, at the time of writing, it's 99 pounds, and for a top rated blu ray player, that can't be sniffed at.
So the good - top class picture and sound. It's not just a player, it's a media centre with iplayer and lovefilm.
DVD's - this upscales very well - but always check if your tv upscales better - my LG upscales better than even this player, so I have it set to output as original source.
An extremely good feature is that this can be made multi-region for dvd's with a simple code programmed into one of those "all for one" remotes you can buy.
So why only four stars? Well, like other Sony's, they've presumably put in a cheap drive, and it gives off a high pitched whine when playing blu rays. Even worse, some players when playing dvd's are really noisy with what sounds like a box of frogs in there. Mine had to go back because of this - in this day and age, it's simply unacceptable to have such a noisy faulty player.
I believe it's luck of the draw if you get a noisy player or not - so don't hesitate to demand a replacement if this bothers you.
