I was the procurement guy for many years, and we had no HVAC guy - we were in a state university, and there was nothing special about the DVDs we bought, they were from Newegg and other retail places, we did buy the most expensive ones because our grants allowed us to, so maybe that's a factor.

I have no doubts (hence my anecdata statement) that there could be bad DVDs in there, or that maybe over a longer time horizon that the media would be cooked.
