Phil,
Your question may get more of a response on the QuickTime-API list...
That having been said, I use +canInitWithURL frequently in my video
management software and I don't experience any blocking when the
method is invoked.
I suspect that +canInitWithURL only needs to read the header of the
object pointed to by the URL before it returns a TRUE/FALSE response.
later,
douglas

I would like to use this as a means for determining how to treat
certain urls in my application, but I do not want the process to
get bogged down if the url needs to be completely downloaded and
interpreted first.
Thanks,
