No, I think in fact that you are wrong. 
Each video driver can support one or several Video Palettes for the
encoding. PWlib supports them all. Compression is something related to
OV511, I simply think that using compression with OV511 doesn't work
with the video palette YUV420P requested by GnomeMeeting through pwlib
and it doesn't return an error. That is why it gives a broken image.

It seems to be a driver problem to me, not a pwlib bug.
