After connecting to The appropriate link, get message "cannot play video," yesterday could not even get to that point. I have tried this on my Android EVO, as well as android Hero...
In the past m.liveatc.net worked great.
I also am having this issue. However, I found that the default streaming player has an issue with this since some sort of update. I downloaded a free player called xiaalive-lite and it plays the feed just fine.
I have Hero running on Android 2.1.
Hope that helps.
