One more question: the ST is on a separate pc. i play music from another ... how can i have the RDS INFO ???
You're making things difficult
If you connect the 2 PC's to a network and share a drive you should be able to use the method described in the Stereo Tool help pages: http://help.stereotool.com/rds_encoder_texts.shtml
(see 'Including dynamic texts').
Warning: There might be a chance that accessing a disk on another PC stalls Stereo Tool too long which could cause hick-ups.
To avoid those, it might be a good idea to have a tool write the names to a file on the laptop, and use a batch file to copy them (for example every second) to the 2nd pc. And then read them locally with Stereo Tool. I don't know if this is really necessary though.
