We have a 10kw generator, but the run to the tv is quite long and the voltage drops quite a bit, I measured it once and it was under 110v. We lost power all day during an ice storm a couple years ago and chanced it with a cheapo dvd player and 27" crt. I wouldn't run anything expensive without one of those high rent ups units made for running av gear. Amie mentioned once that they have days-long outages regularly and run their theater with a gen. I wonder what that setup consists of.
