[MPTF] ADR_Min_Control and minBandwidth

Hello,

To have a minimumBandwidth does not make sense from a control of the the stream perspective. If the stream is of type VBR there is going to be some very odd behaviour with increased quality levels at low bandwidth consuming portions of a stream. If comparing to what is described in Silverlight the max and min related to tracks which I interpret as the levels relating to the manifest. The support of maximumBandwidth is makes sense and should be kept but not minimumBandwidth.
