xwinwrap - loop movie as wallpaper

[yodo]

Hi there,
I'am trying to configure an animated desktop. I run the movies with that command: xwinwrap -ni -fs -s -st -sp -b -nf -- mplayer -wid WID -nosound *movie* -loop 0
The movie works, but I still have two big problems:

1) Every time mplayer starts to repeat the short movie clip, the desktop becomes black. Its only for a very short moment (~1/4 second), but its still disturbing. Of course I could edit the video (make it longer), so that mplayer only needs to start a new movie once in a hour. But that file would be too big.

Is there any way to get rid of this few black frames? For example a movie player that is able to start the new video before the current ends.
If you are wondering why I added the "-loop 0" option at the very end - I read in the internet, that this decreases the black frames before the video is repeated.
Don't know why - it's true...

2) How can I set the xwinwrap wallpaper to the background? I already added the "-b" option, but it still is not enough. If I open a new window, it starts behind the xwinwrap wallpaper. When there is already a window in front of xwinwrap, the new one opens in front of that window. (-> and in front of xwinwrap).

I thought about using the Window Rules in ccsm, but how exactly do I enter xwinwrap there?
Isn't the window-id defined in the xwinwrap start-command? (-wid WID). But that is not working.

Hope someone can help. :)
greetings,
yodo

FWIW.....;)

I am using Giblets Xwinwrap GUI (his "boring meetings project" :p)

The black frames is better with this app but I cannot figure out how to make it perfect. A lot of discussions in above thread.

With the terminal and xprop you can identify the Xwinwrap window

Thanks, but xprop ignores the xwinwrap window and gives this output:

When I start xwinwrap without -fs xprop notices the window.

But which part of the output can be used to force xwinwrap to background with ccsm? (If there is one...)

[yodo]

Doesn't anyone know?
