I was first in line for a PS3 simply for the blu ray capabilities. Bought that and marvelled at how wonderful it was... but it was just too noisy, too hot and too power hungry.
I ebayed that, in order to get a standalone player so I could watch a movie without the washing machine noises of the PS3 fan in the... foreground actually.
For the same money I spent on the PS3 with all that computer power and all those other functions, I bought this BDP S500. Firstly I was unimpressed by the pointlessly huge, hollow, lightweight plastic housing of this thing. Not even a hard drive in there, so why make it so chunky? and I'm also unimpressed by the sliding front mechanism because I know one day, another gimicky moving part to go wrong and stop me from using it for the use it's intended for: playing movies, not being a plastic robot.
The menu is painfully slow, I would almost say it had been dropped on its head as a baby. When it's off, you press eject, walk off to the kitchen to make a cup of tea and when you come back into the living room you almost drop the tea because you'd forgotten you pressed it and suddenly the front drops and the tray projects out.
Pop the disc in, another few painful moments of loading up.
God help you if you need to use the menu function while a DVD or BD is playing because it definitely does not have the processing power. You press the menu button. 5 second later you press again because you think it didn't work. 5 seconds later it pops up the menu then pops off the menu because you pressed twice. Grrr.
But.
The reason I have not sent it back is because the picture and sound quality is amazing. Superior actually to the PS3. It's so good in fact, that I need to rewatch movies I've seen on the PS3.
Also I like the purity of a simple stereo amp. Not a fan of surround. This player has a setting for a 2 speaker setup which is great, because now I can hear the dialogue in movies! my 2 stereo speakers have dedicated mid ranges which went pretty much unused with the PS3, and what was aimed at being for the centre speaker was lost on the PS3 when connected to 2 speakers. Example, The Departed, you can not hear all the slurring speech on the PS3 (regardless of audio settings) and on this player, you can hear it extremely clearly and it is more in the foreground too. Before you would need the volume up so loud just to hear the dialogue, and then suddenly an "action" sound would give you coronary failure (probably much to the delight of the director).
Also this player seems to freeze up when I change channel on the TV or change the aspect ratio on the TV. Remote or buttons on TV itself. It's like it's getting feedback on the HDMI cable. Philips TV by the way.
Oh and what I thought was a problem of my TV, where motion became jagged on slow horizontal panning, was actually a problem of the PS3. BD movies don't do that on this player.
In summary: beautiful picture and sound, it does what it should do and does it very well. But it's a bit dumb and large and Sony has become too fond of plastic.
