What use is gstreamer?

["Patrick Wiseman" <pwiseman@gmail.com>]

Provocative question, I realize.

But here's why I ask:

totem-gstreamer could not handle DVD's with menus, no matter what
plugins I added, it just played the first track.  So, I switched to
totem-xine, and it handled them perfectly.

Rhythmbox (based on gstreamer) could not handle wrfg.org/listen.asp
(told me it could not determine the nature of the stream).  The totem
(now -xine) movie player handles it very nicely, although I really
don't need the rather cool visualization!

I LIKE Rhythmbox - is there something I'm missing (although I think
I've installed all the gstreamer plugins there are) to have it play my
favorite radio station (WRFG)?
