ah thx to both of you .. that seemed to get a little further..

I did a 'ConnectDirect' on the output pin of the file source filter and the
input pin of the AVI Splitter. The AVI Splitter now has an output pin
called 'Stream 00'.

So now I'm attempting to ConnectDirect again on the output from AVISplitter
to input of AVI Decompressor. But I'm getting an error back on the call to
ConnectDirect at this point: VFW_E_NO_DECOMPRESSOR(0x80040255) - Cannot
play back the video stream: could not find a suitable decompressor.
The ting to do is to call 'render' on the output pin.

It is possible that your machine does not support the file format, but
there are some formats which do not use the ACM/VCM decompressors (which is
what I believe teh AVIDecompressor wraps). Digital Video is an example.
Render will try all the decompressors in the system if need be until it
finds one that works.

Another common format that uses AVI is DivX and variants - also not present
on most machines - you may need to install a codec. There are programs
which will tell you what iws in an AVIFIle (AVIInfo may be one).

I'd be happy to try another file format if someone can guide me to build a
graph manually for whatever format they know to work. In the end I need to
make my own filter for a specific type of network stream anyway. But if
none of this works as documented, then I wont even try to make my own
filter.

THe simplest thing to do is this.

find yourself a collection of files.
create a graph
call RenderFile
Next file

see which ones work.

There should be a statement of which decopressors are supplied with mobile
somewhere on the MS site.
