Just now I observed something in my lsmod. I was looking at the modinfo 
of the tuner card driver modules (cx88xx)  and looks like they are v4l2 
drivers. There was another v4l2_compat module for v41(1) compatibility 
layer for v4l2 drivers. Do you think this is the problem? As the driver 
is a v412 driver with v4l compatibilty layer, this would cause prbs. I 
saw an option in pwlib for v4l2, does this help? Or gnomemeeting wont' 
be able to read from the v4l2 drivers?

TIA
