    AMT Support for creating JFIF files at 23.976

    It seems that even though within the Avid environment the progressive JFIF resolutions (14:1, 28:1, 35:1) are available for use in 23.976p NTSC labeled projects, the AMT SDK does not seem to be able to create these resolutions successfully at 23.976 FPS.

    By modifying the shipped XML for 14:1, for example, to show the <framesPerSecond> tag as 23.976 instead of 29.97, any call to CreateAmtFile will simply fail without error.  Is this a known bug in the latest version of AMT?  Or is there a trick to encoding JFIF files at 23.976 using the toolkit?

    Here is the debug log output when attemping to CreateAmtFile with those settings:

    And it ends abruptly there.  Any insight on what the issue might be here would be very much appreciated.
