When talking generalized "best settings," there's really no such thing with TV signals. Not only do you have the usual personal preference caveats, but the quality of both the signal and the external tuner can vary so
much. It's the area where all the "accurate" and "minimal processing" discussion kind of goes out the window, since you want to apply whatever tricks you can just to get a decent picture.
SMOOTH is not something I would use for disc sources, but if it improves your cable PQ, that's great. In your experimenting, looks like you kept it on SMOOTH while testing all the other combinations. Did you try any of the other PC modes, or do you just know that you prefer that one?
You got me motivated... I really wanted to find out which combination of settings resulted in the best PQ for SD CABLE
viewing. Since this source is generally the worst source for viewing, it had the most upside IMO for finding the best combination of settings.
So here's what I did to find the best combination. I got my 15 yr old, sport fanatic, to help in validating what my own eyes were seeing. (We agreed on all the findings below). I wanted to minimize as many variables as possible so I could isolate key settings. For the purpose of this evaluation, "best PQ" is defined as clarity of object motion in the scene as well as motion from camera panning
I was able to find a relatively crappy cable signal for a European Motocross competition. I figured a crappy signal would allow us to see changes in PQ more easily. There were lot's of camera panning shots and lot's of high speed motion from the competitors. This source was excellent for judging motion with flapping shirts, high-speed panning across the scene and fast moving objects.
Next I limited all viewing to the factory STANDARD AV mode with the factory settings. I started with the 4:3 Override set to 480i in the STB. I then changed the Cinema modes one at a time and watched the motocross for about 2-4 minutes to make a judgment about PQ.Cinema mode results:
OFF = some level of pixelation and motion blurr
STANDARD = least pixelation and motion blurr
SMOOTH = nearly the same amount of pixelation and motion blurr as OFF
ADVANCED = About the same pixelation and blurr as SMOOTH and OFF but with an occassional artifact
I then wanted to test each of the STB 4:3 Override settings against each of the Cinema modes.STB 4:3 Override setting:
OFF = somewhat improved PQ over 480i but the picture was much smaller on the 151 (which probably accounts for the better picture). If you increased the picture size using Full, Wide or Cinema in the 151, then the motion was degraded below the performance of 480i.
480i = See Cinema mode results
480p = Poor overall.....much pixelation
STRETCHED = About the same as using OFF and then stretching the picture using the 151's controls. Not very good.
While the results above may appear confusing, the conclusion was actually clear for both of us. If you're looking for the best combination of settings between your Motorola 6416 cable box and your Elite to achieve the best SD cable motion PQ, I recommend the following:CONCLUSION
Set 151 Cinema mode to STANDARD
Set Motorola STB to 480i
You'll still want an Advanced cinema mode for viewing blu-ray, however I would definitely have a few AV modes with Cinema set to STANDARD and your cable box set to 480i. I have now changed my opinion of Smooth for viewing sd cable based on this personal experimenting. I hope that helps others looking to maximizing SD Cable TV viewing.
