This is exactly the same situation as in the example with the BitBand server
you've provided in your last email:

                        %%%%%%IMPORTANT START%%%%%%%%
Media Description, name and address (m): video 0 RTP/AVP 33
Media Type: video
Media Port: 0
Media Proto: RTP/AVP
Media Format: MPEG-II transport streams
Media Attribute (a): rtpmap:33 MP2T/90000

Please note, that raw UDP transport is not suitable for multimedia delivery
over IP networks, since it's not able to correctly handle standard situations
(packet reordering/duplication).

Therefore I'd recommend to always use RTP unless you have a very specific 
problem which can't be resolved in any other way - e.g. a set-top-box which 
does not understand MPEG-TS over RTP. 

	With kind regards,
