Not without help from your ISP which is pretty unlikely for an internet link. You have no way to enforce QoS on the ingress chokepoint which is wherever your carrier is policing to 30Mbps; all traffic is treated equally. This is why many people use private WANs, typically MPLS these days: they can pay for QoS on the carrier side as well as an SLA.
This one I can only speculate on. At 20Mbps the ISP policer would be running at 67% of maximum. If the video stream has an inconsistant bitrate (e.g. more motion typically means more packets) it is possible that short bursts in traffic are hiting the maximum and getting dropped, causing the encoder to view the stream as degraded. Another might be that the ISP has a bottleneck or is actively degrading such a high-bandwidth flow on their network (certain ISPs do this for P2P traffic for example).

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
