hey all, ive been having this problem for a while now and its pissing me off. First off i do have flip4mac already, and im using safari browser. My problem comes when i try to get an internet stream. I have an xm free trial for internet radio, when i click the appropriate channel, quicktime pops up, then alert comes up and says "Alert, the URL is not valid". When i goto www.nhl.com and try to play a video of highlights i get the same problem. Someone help!! this problem is driving me nuts.
