I hooked up my Dish Network 522 to a Samsung 5063 HDTV with an s-video cable and the picture on the TV is poor. (The 522 sends a SD picture to the HDTV.) I switched from the widescreen view to the 4:3 view. Someone suggested turning down the sharpness and that helped, but not enough. Any suggestions? The sad thing is that my wife thinks the picture on our 25in. 1989 Sylvania tv is better....

Bottom line is that SD does look better on a smaller television. That's a sad fact.

I have a model 6000 receiver (Dish of course)... and sometimes the S-video output for SD is better than the Component output... but still, the SD just doesn't look as sharp on my larger TV as it does on my smaller TV.

My 32" looks really nice, when the same broadcast might look like crap on my widescreen HDTV.

Just the same old problem, SD resolution is lower... so at some point you blow it up enough to see the flaws and the compression in the signal.

Another thing to consider is that when you watch an SD program on an HDTV, the signal is being upconverted to whatever resolution you have set on your HDTV. This also degrades the signal somewhat.

Native 480i viewed on a good SDTV (non-digital) seems to always look quite good especially on smaller TV's.
