   I agree with this.  Actually I'm not sure that I even like the way video 
works in noatun.   It just doesn't "feel" as good as QT or MS Media Player 
via crossover.  It doesn't have a nice enough GUI yet.

   BTW, KWinTV rewrite (qtvision) is much the same - a kpart which implements 
our underlying video input and output methods, along with channel management, 
closed captioning, videotext, OSD, etc.    This has a lot of power, as we 
have already demonstrated by making the kpart work in a mainwindow client, 
kicker extension, kicker applet, screensaver, kpart for konqi, etc.  Do you 
think that embedding xine, gstreamer or mplayer will work so well?

   I'm not trying to say that our system is better.  Quite the contrary.  
They're both very different, and both quite good.  For instance, I am quite 
impressed with where Xine is right now (and I have contributed to Xine too).  
I'm just wondering if maybe our video code should go into a generic lib for 
kde apps to use for video.  I already have some ideas and I think our code is 
more suited to implementing them than perhaps the current code.  And I don't 
like jumping through hoops.
