Precisely.
	In the very long Windows Media stream I was working with
originally, I could have:

mplayer -ss 8:54:15 stream.dump

and it seeks right to and starts playing audio at the correct
position 8 hours, 54 minutes and 15 seconds in to the recording.

If I had left it alone, it would have gone on for another 23
hours.:-)

The stream file is about 900MB. It appears that mplayer has no
problem with the size of the file. There is something about that
particular stream, however, that prevents mplayer from figuring
out where to end it if you have the -endpos hr:mn:ss values
there. An mp3 stream from another source worked perfectly with
the -endpos directive. I just had the dumb luck to try the -ss
and -endpos flags with a stream that exhibits this problem.

	Again, many thanks.
