I don't understand why Gnash would be able to play a video by using
the gstreamer library and the codecs it knows about, but Totem
wouldn't be able to play the very same thing using the very same
library on the very same system.  Are you really sure there's no gnash
bug here?  A "Save Media" feature that half the time saves media that
won't play isn't very useful.

BTW, gnash won't play the saved file either, if passed its name on the
command line.  (I thought we'd considered adding a kludge that lets it
play media files as well as .flv files.  Such a kludge would at least
in theory allow gnash-saved files to be played reliably.  Is there a
gnu-licensed .flv media controller movie that we could include in
gnash and invoke in this case?)

I installed mplayer (2:1.0~rc2-0ubuntu13.1) and it indeed can half-play
the stream saved from this youtube page ("3 Year Old Solves Rubik's
Cube in 114 seconds"):

  
http://www.youtube.com/watch?v=tSqUcrFJ498&feature=PlayList&p=D1D5823E1D083AF2&playnext=1&index=2

But it only gets the audio, not the video.  Totem can play it, too,
including the video, and reports that it's using the Sorenson video codec.

But try this page ('Monty Python's "Life of Brian" (Stoned to death...)'),
which is the one that gave me trouble last night:

  http://www.youtube.com/watch?v=R_hlMK7tCks

it plays fine in Gnash, but I get a file that totem won't play, and 
mplayer won't play it either.  Mplayer reports:

I tried with ffplay and got largely the same result (minus the "skipping flv
packet) messages.

While gnash is playing that clip, /proc/nnnn/smaps says that it has
