Yes, you should skip the compression; in fact, you should skip doing the movie in Poser altogether. I usually output my movies as single images and then put them together in GIFAnimator by Ulead. It's inexpensive (approx. $50) and, despite the name, will actually let you create MPEGs, AVIs, MOV, and Flash animations. You can also specify the frame rate so you can slow down your 30 fps animation or speed it up if you want. Neat little program.
