Essentially, the buffer gets nulled out, but it doesn't completely 
re-initialize the player, as I've pretty much said that .nuv can't change 
format mid-stream.  'Course, that may have to change at some point 
(transcoding from mpeg-2, for instance).  Can't you just make the filter seek 
to the 0 position?  Should be fine that way.

Backtraces would be cool.
