I'm not going to bother commenting on the content of this DVD, because even I feel it is an insult with all the errors and factual mistakes. First the most annoying error -- he has a group sitting in one room talking about the Holocaust without noting that almost every person who ever worked for or was persecuted by Nazis was Jewish, making no distinctions at all: they were all Jews.

Bought it and used for a few days to watch TV....nothing too fancy or anything......until one day the screen started making this 'buzzing' noise, which is like you getting sick when using your computer.....if u turn off all the peripherals from ur computer then shut down ur pc. Then what do ya know???? It never turns on again!!!!!!! I checked my power supply and..... nope, not working. What else can happen during powerup?....

I read all the reviews here, and although most people seemed to really like this machine, they were probably swayed by the overwhelmingly positive ones. I'm sorry. It's junk. There is no way we could have used it without a lot of very loud grinding sounds. The plastic grinder chamber was so tightly packed, though, that you would actually be unable to open it, except with a hacksaw or similar tool.
