I just upgraded to 7.3 -- not happy.

When I output a sequence as MP4 it defaults to 30fps and the frame rate seems to be accurate (10 seconds on the MP4 matches the images in the Iclone camera).
When I output an image sequence of the same file at 24 fps it renders 240 frames (correct) but they play back in slow motion.  It appears that Iclone is not interpolating the way it used to (in 7.22 when it worked).  The 24fps image sequnce appears to be the first 240 frames of the 10 second sequence, and not the interpolation (skipping frames).
Another example at 12 fps demonstrated the same problem -- when played back at 12 fps the motion was clearly different to the original.
And the sequence no longer stops in the selected range (in this case 1-600) but keeps printing.
I have to work at 24fps, not 30 or 60.  This seriously screws me up.
