Although, now that you mention it, I am wrestling with a very strange runtime
exception related to the FLVPlayback component in a project. I have a custom
resizable Panel containing a custom Flex component which contains an FLVPlayback
component encapsulated by UIMovieClip.
If the source URL is invalid, and we try to call flvpb.setSize(), we get a RTE
every time, which totally buggers up the application. It's consistent and
reproducible, and only happens when the source is invalid. (I can't wait for
Flash 10 when we can catch thrown RTEs)
TypeError: Error #1009: Cannot access a property or method of a null object
reference.

fl.video::VideoPlayer/http://www.adobe.com/2007/flash/flvplayback/internal::doAutoResize()
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()
Since there is a very minor case scenario where the URL might not be correct,
the only solution we've figured out has been to "pre-qualify" URLs in the
application by trying to establish a NetConnection to the URL, and then marking
that URL as "good" before the vid player ever gets to use it, which is a nasty
kludge.
Do you think this might be a Flash-Flex integration thing, or simply an
FLVPlayback component bug?
