I always render to images files when using Poser or Vue ... the image quality is substantially better, and if you like you can treat the frames in a graphics app (e.g. Photoshop.) Apps like Quicktime Pro or Virtual Dub make it easy to turn the image file sequence into a movie file. I use the free Zoom player (available from www.download.com) for most of my movie file viewing. When saving to .avi format, I prefer the DivX codec. (www.divx.com)
