In todays www.widescreenreview.com is a link to an article in TWICE about 3rd generations STBs which incorporate the recent refinements. They promise greater sensitivity and multipath rejection. However, the only STB mentioned is the Zenith with its 3rd gen demodulation chip. All the other products seem to be sets w/HDTV tuners built in. Zenith is already working on its 4th gen chip. Another indication that the Zenith STB will be the one to buy...when it comes out?
