I have been listening to Sirius just fine with my F4M plugin. Two days ago I was told an update was available. I updated. Now when I go to listen to Sirius, I click on my fave channel and QT starts and I get an alert that says "URL not valid". I have seen many post this same problem but nothing works for me. I have fiddled with the settings, reclaimed F4M as my default player. Nada. I am running Mac OSX 10.4.11, QT 7.6.4 and F4M 220.127.116.11 Whoever gets my Howard back on will get a ginormous virtual hug!
