Can't stand the big BLOOP and uninspired Online interface.
Stream_on seems to work fine for me on XP Professional.
I did try to load it on the wife's Vista-based laptop and couldn't even install it.
Vista sucks though and I hate it.
Did it install successfully? If it did, then you should be all set.
Put in your SIRIUS user ID and password in the upper left corner, and check the Remember and Auto-Login boxes (if you want the program to save your user name/password and automatically log you in when you run the program).
"Add Favorite" adds the channel you're currently listening to your favorites list (which is located in the "Category" drop-down).
"Manage Favorites" is to remove a channel from your list (double click to remove).
"S-Store" will store the ID of the song you're listening to at the time in your "Song List".
"A-Store" will store the ID of the artist you're listening to at the time in your "Artist List".
"Manage Stored Songs" is to remove an artist or song from your list (double click to remove).
Checking the A-Seek (artist) or S-Seek (song) boxes will have the program actively seek artists and songs that you've stored in your list and the program will inform you when they're playing on another channel.
The tone check box will have the program emit a 'tone' when a favorite song or artist is playing now.
I think I covered everything... Let me know if you're stuck or if you have any questions.
