only thing different is now it is winxp and it is still working. that's a long time of constant running of the fm transmitter.
in all that time it is only just now some one some place started using the same Freq i am using now i get some sort of bleedin from time to time but it can't block out my signal since mine is closest to my stereo.
all this time i've found limits to the amout of usb plugins that can run at the same time by way of it losing power through them and causing some issues with the mm 3 version such as crashes or it crashes the usb hard drive, so no big deal i didn't need all the usb addons anyway, i just mentioned it so if anyone else has two or three usb hub's loaded and wonder why they are having trouble with mm or some other software that uses lots of memory, it might just be a power drain through your usb addons.
