If you have a real program ID, you'd use:

<episode-num system="dd_progid">your progam id value, possibly with 
authority</episode-num>

and note that you can specify an episode-num for both systems, dd_progid 
and xmltv_ns, for each program.

I don't think we have a means of specifying the series ID with the XMLTV 
parser, currently.  I know Gary Burhmaster was doing some patches to 
improve the XMLTV parser to allow more data, but I'm not sure if he 
included a patch for specifying series ID (let alone if the XMLTV spec 
even allows a place to store it).
