[LAU] recordmydesktop with jack2

Hi I'm trying to capture a screencast of a jack2 client (renoise), but it seems recordmydesktop and jack2 doesn't work well together. Anything I should do different? Any alternative to recordmydesktop that I should try instead? I'm running ubuntu 12.10... atte@blokhus:~$ jackd --version jackdmp 1.9.9 Copyright 2001-2005 Paul Davis and others.
