Emilio,
we should focus at first to the problem why we do not reach the connected state.
I think I have been experiecing similar problems from time to time. However I do
not understand how this could be related to the different video sources, since
for OPAL this should be completely transparent. Maybe its a good idea to
continue tracing the establishment process? And, to be sure, put a trace when
going in and out in the functions of src/devices/videoinput.cpp (However I am
unsure that the problem is there since you do get a working picture) to see if
some (of my new ) functions block there.

About the X BadWindow problem I have no idea now, perhaps a -d 4 tells more when
running into that situation?

By the way I noticed on your logo transmission screen that you are transmitting
about 1 mbit/s to the ekiga.net, but only get back 200 kbit/s, thus the garbled
picture and low receiving framerate. Perhaps you should adjust the sending
bitrate to your internet uplink speed?
