My memory has faded, but i believe it shows within the source or by monitoring of traffic.
Various utilities will show download attempts like this, for example:
Code:
h..p://cdn.be-at.tv/003311/004001-0128/005376-1000/0000.beat
003311 is the session
004001-0128 is the audio and bit rate
005376-1000 is the video and bit rate
For any other video, just plug the respective values into the urls provided in previous post.
