Elecard IPTV Player SRD last version supports Closed Captions and SAP functionality.
Closed Captions can not be recognized by WMP, course WMP does not render all Decoder's pins(Closed Captions pin in our case). You can use Elecard MPEG Player or Elecard IPTV Player to play the same streams and to see CC.
Please clarify what do you mean under your questions about server:"On the server how do I enable playback/resume or bookmarking functionality"
