turntable animations

For some reason, maya will not let me render an animation in either quick time or avi format even though I have installed the codecs for both the formats. There is absolutely no reason why it shouldn't let me do this except if there is a bug in the software either way I have submitted a bug report to auto desk, but I don't expect them to solve this issue any time soon though. There fore I have rendered the turntables in png formats and imported them to adobe premier, so I could export them as a quick time movie.
