Super-Bug: Quicktime export in Keynote 6 is faulty

Unlike the great export to Quicktime feature in Keynote 09 we now have a bunch of bugs in a basket called "Keynote 6".

Movies are not anymore played to their physical (or trimmed) length - the automatic transition time stops the movie playback in the QT-export file after the time given for an automatic progress to the next slide - regardless of how long the placed movie file is. We need this essential feature back, because without this we can't export presentations to QT for standalone use.

The only workaround is to set an Out-animation for the placed movie, but then later in the exported QT file the image is stuck after a few seconds (while sound is running as normal). So this is not working either.

And even worse: alongside the right edge the exported QT movies flicker visibly if there are backgrounds in the presentation other than white.

Please repair!
