Do you notice much of a difference? What's your take on the Zinwell's PQ compared to the Pal, or even the Zenith if you have one (and how big is the TV screen you're comparing them on)? I think there's only been one comparison that I know of so far that puts the Zinwell close to the Zenith, but that's only one person's opinion, so I don't know what to make of it (could've even been your opinion - I don't recall).
This could be really important info for some people, but I never see much in the way of comments on the PQ by people who have actually compared it to any other boxes head-to-head. At least very thoroughly. Thanks.
I used a 4-input composite switch connected to a composite channel of my 27" Sony WEGA to compare the PQ of the Zinwell 970A, the TR40, and Directv local channels. Also compared to TV's analog picture. Comparison is subjective and complicated by the 2 second delay between the analog and CECB output and the 5 second delay between the analog and Directv local channels.
All sources produced a good, acceptable picture except the low signal strength channel 36. The analog signal was best for this channel because it was viewable with overall random video noise. Both CECB's pictures were unwatchable because of pixelation. The PQ of both CECB's was the same. The PQ of the Directv local channel was slightly better than the CECB's. The analog TV was the best because of the sharpness of edges (better frequency response from greater bandwidth), lack of artifacts, and infinite colors.
channel---signal strength------ Signal quality
--10.1-----70 to 85---85-------100
--12.1-----78 to 93---85-------100
--36.1-----58 to 64---61------ 4 to 24
--64.1-----69 to 73---70------36 to 45
--69.1-----74 to 78---85------59 to 61
The Zinwell signal quality indicatior doesn't make sense to me. If it is a function of bit error rate (BER), I would expect channel 64.1 to be near 100. Could it be a function of the quality (HQ, SP, SPP, EP, XP) of the encoded signal it is receiving from the station? I had an "EP" quality picture with a signal quality of 10.
