Hello, I was having similar problems a while back.  I don't remember
the exact symptoms, but I was encoding, like you, from the example
script with an ivtc filter, and had the same skipped frames/jerky
output problems.

The only thing I could find that fixed it was to reencode the audio -
not using -oac copy but rather -oac mp3lame.  I still have no idea why
that helped, but it certainly seemed to.  See if that works for you.
