Hi Brian, If you only change the PREPARE lines then you are still probably working under the old lab805 version.
This link shows what needs to be present for the new version of the lab to be recognized: https://code.jsoftware.com/wiki/Labs/Migration If this is the problem then when the first lines of the lab are adjusted the NB:labprepare: command should work as expected. There are other issues that show up with Chapter numbering though, because of the way that 'skipped' lines are not counted. In my video labs, I resorted to doing my background work in a separate script which is loaded up front from a different locale. This keeps the base locale clean, but allows the lab locales to be available to the user. It also allows me to run video in console, jqt and jhs environments because I can do a check on the environment in which the lab is being run and load appropriate scripts. load '~addons/media/videolabs/catalanjqt.ijt' for the jqt version of the lab and load '~addons/media/videolabs/catauxjqt.ijt' for the auxiliary script that I use instead of NB.labprepare: the video commands can be found by load '~addons/media/videolabs/videolabjqt.ijs' Hope this is helpful.
