I'm REALLY happy to see this thread!
I love MMW4 (gold) and use it all the time. However the streaming is less than fantastic.
The solution described above is fine for a stream URL. However in my case some radio stations change their URLs/ports over time. What I need is the ability to save a URL which results in a .pls or a .m3u file. MM would then process the resulting playlist file.
The odd thing is that MM already does this (partly). If I go to File-->Open URL and enter:
http://www.foo.com/GenerateAPlaylist.pls
then MM properly pulls down the playlist and populates the "now playing" queue with the entries from the playlist.
What I can not do is add the
http://www.foo.com/GenerateAPlaylist.pls as an entry in the library.
Please tell me that I am missing something simple and it can be done!?!?!
