By default, the allowall ACL sets IPv4 and IPv6 traffic to Low Queue.
According to the 6.4 User Guide, page 367:
Queue (optional)
The queue in which a packet matching this rule should be placed.
Select High for higher priority data, such as voice, and Low for lower priority traffic.
So, just set the laptops role with an ACL pointing to those video servers with the Queue set to High. Unless you want to throttle the other users in that area.
