I have the worst luck. My 700 went bad (just was slow). They brought out 3 100s already. Everyone of them could not get a good signal on tuner 2. they tried my other 700 and it worked great. the 100 keeps rebooting every 30 minutes as well. they are brining a 700 today, hopefully that will work. anyone else notice wierd things with the 100 on tuner 2. my tech said tuner 2 is a bit lower on the 100 model. is that true?
