DirectShow source filter

CodeGuru's snake sample prog doesn't work, it hangs
to register or unregister a filter (e.g.
regsrv32 /u
then draw a filter graph using graphedt.exe
to view, connect ball -> video renderer
to create AVI file, connect ball -> AVI mux -> file writer
this works fine, but important questions remain
1) how do you run the filter chain without using graphedt?
2) how do you get the app to communicate the frames to the filter?
3) where does the source filter's GUID come from?
