Hope this is the right place for this thread. We have 2 720P plasma tv's-one panny and one sammy. We have many standard DVD's. Both of our tv's have upscalers I believe. The quality of the DVD's are less than appealing(no where near as good as the direct tv HD). Would buying a Blu-ray to watch these old DVD's upscale better than the tv or is buying an upscaling dvd be better than our current situation with the tv upscaler? Will either approach the HD we get from direct tv, thanks.
