This has nothing to do with the port numbers since this dissector is
heuristicaly added to UDP (and TCP). 
The sample capture shows "DPlay player to player message", which follow from
this somewhat poor heuristic:

    /* There is a player to player message that does not contain "play" */
    token = tvb_get_letohl(tvb, 0);
    token = (token & 0xfff00000) >> 20;
    if (token == 0xfab || token == 0xbab || token == 0xcab) {
        dissect_dplay_player_msg(tvb, pinfo, tree);
        return TRUE;
    }

The RTP sequence number just match these tokens.
