I use the PDA Module for LabVIEW to run programs on Windows CE and Windows Mobile. You have to use a PC for the development and building of the application, then either use ActiveSync or copy the .exe over to the CE device. There are some limitations in the code and the user interface, but most things work fine.
I haven't actually tried video yet on CE, perhaps that is something I can play with soon.
Good luck!
