The current final releases of VLC are compiled against libdca and support playback of this kind of media.
VLC's current trunk misses this compilation flag right now, but this will be put back before our next public release. (No idea for the nightly builds just now, as I'm already glad to see working at all...)
About the nightly builds: we had to restructure both our internal build system (configure, makefiles, blabla) as well as our server structure. Something is still missing on the latter, but I'll keep an eye on it in the next days. For the meantime, a current nightly build for each platform was uploaded today and a second is about to follow tomorrow noon (CEST).
Please bear with us and keep the fact in mind, that it's holiday time and some server admins may not be reachable for that reason
Ah, and no: your libdca issues are not related to QuickTime in any case. QuickTime compatibility issues only result in video distortion, but nothing else. Try resetting your preferences, plugin cache, etc. by using the script provided on VLC's latest disk-image.
