People with problems with the audio on the beta, it is a gstreamer bug. To fix do this: download http://dl.dropbox.com/u/219349/libgstrtp.so and put that file in: /home/user/.gstreamer-0.10/plugins/

You will probably need to create that directory first. Once you have done that, restart your phone (or if you know what you are doing kill the process /usr/bin/mafw-dbus-wrapper mafw-gst-renderer) then go to the beta website and try watching an hq or lq channel from it. This will fix the audio stutter.

I will work on a nice way of packaging this so it doesn't interfere with any system package, but you can use that in the meantime.
