I'm having trouble watching streaming videos. My mac is OS X version 10.4.11. I've tried with the Safari and Firefox browsers and in Quicktime but I can only hear audio, there's no picture just a white screen. The info for the video file: Audio codec- WMA 9.1, Video codec- WMV 9 Advanced Profile. I came across some sites saying that this video codec is supported with Flip4mac so I don't understand what's wrong. I'm running the newest version of Flip4mac. Can anyone give me some advice on what the problem could be?
