After following your advice, I went back to basics, and have discovered that if I did not set the (mpeg4) config attribute in the sdp, the effect was that my on demand server went a little funky if more than 1 client connected. The setting of the config flag was next on my to do list. But because of this find has jumped to the forefront.<BR>
<BR>
I am limiting the amount of code I am writing to extend the library to my needs, and only doing so through subclassing. I just missed the need for the SDP to be generated from my mpeg4 source, luckily there is the getAuxSDPLine function I can overload to accommodate this. <BR>

No, what you were trying to do originally (set the "reuseFirstSource" parameter to True when you create your "ServerMeiaSubsession" (subclass) objects) should work so you should stick with this. However, you should begin your testing with an unmodified version of the code, reading from a existing data source implementation (e.g., from a (file or stdin) "ByteStreamFileSource"). (Once you've modified the existing code, or written new code of your own, then it's less likely we'd be able to support you.)<BR>
<BR>
You should note also that for some media types - e.g., MPEG-4 video - the input source will get opened and read twice (once for the SDP 'config' information, and once for the stream itself), even if "reuseFirstSource" is True. Your input source needs to allow for this (dpending on the media type).<BR>
