Simon,
I've traced down using the VS 2003 debugger, and the function which is being
called is H323VideoCodec::SetmaxBitRate(), because the function
OpenVideoChannel() receives a reference to H323VideoCodec, not to
H323PluginVideoCodec. You can see this easily setting a breakpoint in this
line codec.SetMaxBitRate(videoBitRate * 1024);, stepping into it and seeing
the call stack. Here it is:

Asunto: RE: [h323plus] MyPhone 0.4
Released
H323PluginVideoCodec::SetMaxBitRate() sends a
messages "Max Bit Rate" to the
plugin codec to set the maximum bitrate.
This function also overrides
H323VideoCodec::SetMaxBitRate() since
H323PluginVideoCodec is a descendent
of H323VideoCodec so the problem
most likely is in the plugin codec not
setting the max bit rate. I
suggest you look at the H.263 plugin codec
perhaps there is something
missing.
