Per Neil's suggestion I'm re-posting this from the WMP General group. I am working on video functionality for an online store in WMP. When a user clicks on a video link, I play a short video ad (served by an ad server) followed by the video they requested. The playlist looks like this: <asx> <entryref href="www.myadserver.com/someadparams" /> <entry> <param name="firstValue" value="tastyData"> <ref href="www.myvideoserver.com/somevideoparams"> </entry> </asx> The entryref comes back with this: <asx> <entry> <ref href="whatever"> <param name="secondValue" value="tastyData2"> </entry> </asx> Here's the question: I need (client-side) access to parameters from both the parent playlist and the nested one in order to render my HTMLView page completely. Is there any way to iterate over the playlist on load - *including nested entries* - and grab these values? Or do I have to wait until the player actually gets to that entry and then use currentMedia? I've set it up that way for the moment but I'd really rather process everything at once. Neil suggested that I might be able to get at it through buffering - can I maybe force buffering of everything in the playlist when the page loads? Many thanks if you can help…
