I have had similar, yet dissimilar issue with my HVAC as I did not have DVD in the slot but a CD. To me it seems like a communication error on the MOST bus. Should be interesting to hear what your dealer has to say about it.
I was not able to replicate the dead HVAC panel as you are able to so here's hoping that they can narrow down on the root cause.
