Part of the problem is that tuners have become commodity items. Manufacturers 
use whatever they can get at the best price, and often change tuners like we 
change socks.

Even the venerable Hauppauge PVR series used many different tuner modules 
throughout its lifetime.

You can't assume that just because one particular unit works well, another one 
with the same model number will also do so.

So if someone reports "great sensitivity" with a particular product, you can't 
assume that the one next to it on the shelf will perform as well.

Some people have reported that the HDHR is not as sensitive as some other 
products (though specific data is lacking), and others have said that recent 
production units are somehow "better". I take such reports with a large grain 
of NaCl. I use my HDHR with a cable system, where levels are generally high 
enough to not be a problem, I've been very happy, but someone using an antenna 
might have a different opinion.
