I can help you.The problem IS Microsoft Video(it automatically comes up when Poser4 opens the window to choose what video you want) .I wrote Curious 3 times!To ask them what to do and their tech gave me rude and flip answers.SO,I figured it out myself.When the window for make movie comes up in Poser,check either CinepakCodec by Radius or Indeo Vid 5.0.I think the Indeo works EXCELLENT.I set the compression to 100.The picture is clear and non pixely in my avis.
