I have Vista (32bit) and got it as soon as it was available!
I had no problems setting up my RU990 (TSU7500) or My Marantz RC9500 and have loaded all versions of the editing software and used it on TSU2000 and on RU950 & RC5400 and not had any issues. The only issue I had was a lack of a serial port for the TSU2000 and my Pronto Neo. But that was the USB problem NOT Vista!
As far as 64 bit Vista goes, that is a whole new ball game and I would expect issues there as it is a different OS in reality.
You can't blame Philips entirely although they are nothing special when it comes to support.
