title: How to encode a .wmv file that XNA DirectShow will play properly?
body: <p>I'm playing around with XNA DirectShow to stream a video from a file rather than loading it into my project (I'm fully aware of the XNA MediaPlayer class by the way). It plays the sample video it came with no problem. When I try to make my own .wmv from a series of PNG files I have using ffmpeg the video plays but is all blue (should be mostly yellow). Pixel format wrong? Wrong codec? I'm certainly no expert in these waters..</p>
  
  <p>The sample video is a VC-1 WMV3 apparantly, and I don't think I can replicate that? What encoding/codec/fileformat should I be using?</p>
  
  <p>Also! If transparent video background is possible, that would be amazing. Is it?</p>
