Hopefully the patch for pwlib stable found on www.gnomemeeting.org/snapshots should fix that.

It is not the same problem : 
formerly, you had to launch the xawtv program to make the video device work,
but now, the video device is not selectable anymore. It means that it is
not auto-detected. There must be a bug in the auto-detection routine
in video4linux.cxx. Can you try to see what happens ?

Am I right if I say that the device is not selectable ? If so, it is because
it is not detected.

So, I understand your problem like that :
- in 0.12.2, the device was detected, but unusable without xawtv
- in 0.84, it is not detected anymore

Right?
