In Fobs_jmstudio.exe when i use transmitter to sending mpeg file
At tab Video
the "Encoding :" show only H263/RTP and JPEG/RTP
but i want to use MPEG/RTP
I added com.ibm.media.codec.video.mpeg.MpegVideo
        com.sun.media.codec.video.mpeg.Packetize 
        com.sun.media.codec.video.mpeg.Depacketize
What do i have to add to registry properly to use MPEG/RTP
thank.
