I received a missive from Brian, a Boing Boing reader working deep inside the heavily fortified bunkers of RealNetworks. After he took me to task for continuously whining about the poor performance of the RealPlayer on my computer, I told him that if he could help me configure RealPlayer not to choke like an earthworm trying to swallow a pig that I'd issue a public apology.
He told me that my problem "could be a firewall issue or an AirPort version problem."
Preferences -> Transport -> Use manually configured
Click Configure and clear all transports except HTTP
I did as he instructed and tried watching a video on RealPlayer. It played without a hitch, which is the first time that's ever happened.
He pointed out: "Just so you know, there is a note about the Airport problem in RealPlayer Help under Network/Connectivity Issues titled AirPort wireless issues."
Thanks Brian, and I apologize to you and your co-workers who strive to keep it Real.
