Hello,
in my previous email I forgot to indicate the video that i want to use. It is miss.h263, maybe that help you to know why I can't transmit it. I put 34 in preferred video encoding, in the Sip communicator configuration, and all others parameters (except the name of the media source, of course) are the same that in case the source is .mov, in wich case that works ok.
Thanks,
Almudena
