Ok, here are quick instructions to test, it isn't too hard actually. I just tried it myself and passthough seemed to work fine for xvid, but rest not so much. On your N900, run the following command as root:

Then use your browser and select your profile from the dropdown list and start the stream. It doesn't have to work on your browser, most important thing is that it starts the stream (switch to log_level 1 and start Knots in terminal if you want to see the stream address, but it's usually the one listed below)

Then on your N900, run the following command (on same line):

Stream extension depends on stream_extension field in the profile so if you use ts mux and ts extension, it's stream.ts. Try different muxes that can be used with http (ts, ps, asf) and see what plays and what doesn't. If you get h264 working with gstreamer fine, I could consider switching to it on N900 version of Knots.
