AVI render problem solved! Thanks for the push, guys (esp. Little_Dragon), something finally connected in this little brain of mine. I reset the color depth on my video card from 16bit to 32bit, now the AVI renders just fine. No clue why this would matter (shouldn't the render be a straight computation process, no video involved?) ... but it clearly does and now that the problem's fixed I can go screw up something else. :-)
