I've been having troubles with importing AVI footage into Poser 6.  I am rendering animated Terragen footage, then bringing that footage into Poser so I can sync camera movements with Poser characters (thus bringing Poser into realistic landscapes).  My problem is that at certain points in the animation, the background footage will simply freeze for about 2 frames before continuing.  It's very strange, and I've always had this problem with background footage in both P4 and now P6.  I have absolutely no clue what the problem could be.  The AVI background itself is rendered uncompressed at DV resolution (720x480), and the Poser window I work in is also 720x480 to ease the pain on camera sync.

If anyone has experienced this problem or can help me out, I would appreciate it a lot.  Thanks!
