If it's his server, then why do Quicktime files play just fine on my

I have no idea, sometimes some combinations work and others don't, and
sometimes it's just the karma of the user. But since I have been
watching streamed QT movies from a myriad of servers with no glitch, and
since there are obviously many others who have a problem with his
server, the conclusion that the problem is at his side is valid.
Besides, if there's one installation with an absolutley clean QuickTime
environment with the newest components in the universe, then it's
certainly my Mac.
