Hi,

No, I do not, but you can do those tests yourself if you get an A/V receiver and a compatible TV display that has component video inputs. If you want HDTV, the TV display must be progressive-scan compatible. You could plug the component-video outputs of your DVD player directly into the TV display, bypassing your AV receiver's component-video switching, then use the receiver to switch the component-video output of your DVD, comparing the two to check for any picture degradation.
