I agree with Chris any level of looking at forums would have made it appearent that UV only offers 2 HD streams. I guess I have been around too long (old) but I never really bother reading much of the marketing literature. I always go to the forums first and see what is being said. If there are any issues no matter how small there will be tons of threads discussing them. As for having 3 or more HD TVs this is really irrelevent to the installer since you can certainly watch HD or SD on those sets. We have three in my house and if we have 2 HD streams in use you either watch something recorded or watch it on SD.
