	I know about this issue. In fact, my Windows does not get the "changed
position" or resized event. May be I have forgot some parameter when
initializing it or I have handled some previous events wrong. Does
somebody who knows the Windows API have any clue?

> 2) crashes after a few minutes 

	Yes my windows build is very very unstable. I will look into it. I not
sure it is in the sinks, it seems to me there are some problems also in
other plugins.

	Yes, I have the problem with popping too. As for too fast audio
playback, I have seen this issue when the audio file had unsupported
audiorate, but I have raised the limit to 100000 what should be enough
(or not?)

	You must add queue element between threads. The correct command is
gst-launch.bat filesrc "location=E:/video.vob" ! decodebin
"name=d" { d. ! queue ! ffmpegcolorspace ! videoscale ! ddrawsink }
{ d. ! queue ! audioconvert ! dsoundsink }

I will try to test test some .vob files. My be I have shipped the old
version of dsoundsink which supports frequency only up to 41000Hz. (I
have some other work now but I will look into it this afternoon). You
can also try to add audioscale element before dsoundsink

On no, this is bad. i do not have an idea in the moment :(
