I posted this in the Rear Projection Forum, but didn't get any responses and realized I probably should've posted it here instead. Sorry for the double post. Anyway, have a Samsung 1080p DLP TV and my understanding is that DVD players using a Faroudja chip cause macroblocking in these sets (I have seen that first hand). As a result, many have recommended DVD players that do not use this chip when pairing it with this DLP set. I've also read a number of posts that recommend setting the DVD resolution at 480i and then letting the TV do all the upscaling. However, I believe that this Samsung TV also uses the Faroudja chip and therefore wouldn't this type of setup be likely to cause more macroblocking than setting the DVD player at 1080i and then just let the TV bring that to 1080p?
