by the way, i've been contemplating if i should sell my ps3 and get a stand alone bd player, is there really much of a difference? or would it be better if i just purchase the ps3 bd remote and use it as it is (for games and bd's)
What's a tempo controller? Hmm...it's sure a weird ques.
As for the PS3, it depends on your personal preference if you're using your PS3 for watching movies, playing games, listening to music/songs, etc.
For me, PS3 is a very versatile machine, I use it to display all my photos in my HDTV so the whole family can view them. Also from time to time I play games & listen to downloaded music.
As for a BD player, I'm very satisfy with its performance but for those who watch lots of BD movies & own HDMI AVR capable of decoding the DTS-HD MA might want to consider standalone BD player that can output the audio bitstream in order to take full advantage of their HDMI Receivers.
