Is is possible to improve the pq of an EDTV 20" Samsung LCD? It is currently running it thru s-video on satellite & the pq is very good, but I was wondering if it can be better thru a scaler or any other method. I run componnet video on the dvd, but is there anyway to upconvert cable to component pq? Same question applies for my 34" HD Sony rptv. How can I get the best pq w/o an HD reciever.
