Replicating Youtube Behavior

[DotProduct]

I am trying to make this library work much in the way that it does within Youtube. Such as, what is the default "iTag" used by a player. Is there any knowledge of what algorithm is used to determine which tag to play?

Youtube will give you a lower resolution track if you do not have enough bandwidth, this allows for better performance even though the quality may not be the best.

Does this library get this type of information?
