viewing a "motion" webcam stream

[xbianusr]

I have a webcam running "motion", which outputs a mjpeg stream at about 1fps. Not super fast.

I'd like to view this stream on Xbian. Others have tried to use different webcams and have purportedly had success with something like this:

1) create a .strm text file
2) enter the IP address of the stream, something like this:
http://192.168.1.3:5225/?action=stream&ext=.mjpg
or
rtsp://192.168.2.22:7081/videostream.amp

The closest one I've been able to get is the "http://..." method. But it doesn't work quite right. XBMC seems to try to buffer or collect many frames of the mjpeg stream, then play them back really fast (maybe at 60 fps). The result is I see a still image of the webcam for about a minute, then all of a sudden I see several seconds of very fast time elapsed video of the webcam stream, then another minute of the still image.

I've tried a few other xbmc settings like:
<buffermode>3</buffermode>
<overide><fpsmin>

but these didn't seem to have any effect.

Any way to get XBMC to display the mjpeg as they are downloaded? Is there a neat add-on that works? My efforts so far haven't gotten me far.
