I've changed the bitrate parameter to 1500 and tr_fps to 30 in

GMH323EndPoint::OpenVideoChannel (H323Connection & connection,
                                 BOOL is_encoding,
                                 H323VideoCodec & codec)

in endpoint.cpp. This mean max bitrate of 1500 * 8 * 1024 ~= 10mbps  and 
30 fps

Still its the same. Video is all choppy. Can't we get smooth video in 
gnomemeeting using any codec. I've tried with H.261 and its worse. Is it 
possible to get a smooth video with decent VGA quality in gnomemeeting?

TIA,
Sanjay.
