  Make a webserver
  
  put message.png on it
  
  
  
  You add all that to the END of your current mainmenu.js, popup.js, common.js, and trailers.js
  
  THEN REBUILD....
  
  then you can add the new data to your playlist resources...
  
  then anytime you put this in

  "http://192.168.1.1/network/message.png" anywhere in your XML that you want you will pull from that address...(it actually gets cached on load from your playlist resources)
  
  Now we need to get streaming video working !!!

  In order to display the image you need to put it in the filecache first. PS_URI is the image in the persistent storage, FC_URI is the image in filecache.

  sammaz-

  In the displayImage() function, I notice you have a line:

  FileIO.copy(PS_URI, FC_URI, true, cbfn);

  What is the purpose of this line Where does this line copy the file to

  Thanks in advance.

  I have been throwing every format of video at it and all I have been able to do is stream 1 .png image...I get "Unable to load surface from specified file" ...happens for all video...images appear fine.

  here is the snipet for network images
  
  

  //Listeners
  try

  function checkUpdatedImage()
  {
  	//Check if the file is in persistent storage
  	checkFileInPS(URI_PS);
  }
  
  function checkFileInPS(pFilename)
  {
  	try
  	{

  Haven't hit the forums in a while but just wanted to say that some amazing networked applications are coming to retail HD-DVD soon. What I saw today blew me away. Wish there was a way for us to test this stuff without aacs...it would really help at this point.

  Would you mind posting some samples

  You can use WMV files with the simulator, but you need to use S-EVOBs for the actual video content. S-EVOB video can be encoded in VC-1, MPEG-4 AVC, or MPEG-2, similar to primary A/V, and audio can be DD+ and DTS-HD (as well as some optional codecs depending on player support: mp3, MPEG-4 HE AAC v2, WMAPro). There are also total transfer rate restrictions to consider, though if you're streaming the A/V you likely won't hit these.
