When reading replies re. tv set up often it is suggested to defeat or turn off the Scan velocity modulation feature on the set.
Even in the reports in sound & vision they refer to the fact that the best results in picture quality occur after the svm has been by-passed.
I was under the impression that the svm was a good thing that enhanced the picture and extended the life of the set.
Why do I want to turn this off?
Also can any one suggest optimum picture settings for a Toshiba HX83 set up in a basement HT with no natural light intrusion.

Thanks Ken
